    263266to operate upon it.

    264269
    265270The building block of a scantable is an integration, which is a single
     
    284289
    285290\index{Scantable!contents}A scantable has header information and data
    286 (a scantable is actually an AIPS++ Table and it is stored in Memory
    287 when you are manipulating it with ASAP.  You can store it to disk and
    288 then browse it with the AIPS++ Table browser if you know how to do
    289 that !).
     291(a scantable is actually an AIPS++ Table and it is generally stored in
     292memory when you are manipulating it with ASAP.  You can save it to
     293disk and then browse it with the AIPS++ Table browser if you know how
     294to do that !).
    290295
    291296The data are stored in columns (the length of a column is the number of
    292297rows/integrations of course).

     299{\bf [MALTE: Is this outdated??]}
    293300
    294301Two important columns are those that describe the frequency setup.  We mention
     
    304311the flags, the Tsys, the source names and so on, but those are a little
    305312more transparently handled.
    306 
    307 \subsection{Management}
    308 
    309 \index{Scantable!management}During processing it is possible to create
    310 a large number of scan tables. These all consume memory, so it is best
    311 to periodically remove unneeded scan tables. Use \cmd{list\_scans} to
    312 print a list of all scantables and \cmd{del} to remove unneeded ones.
    313 
    314 Example:
    315 
    316 \begin{verbatim}
    317   ASAP> list_scans()
    318   The user created scantables are:
    319   ['s', 'scans', 'av', 's2', 'ss']
    320 
    321   ASAP> del s2
    322   ASAP> del ss
    323 \end{verbatim}
    324313
    325314There is also a function \cmd{summary} to list a summary of the scantable.
     
    349338refer, is always listed.

     340\subsection{Data Selection}
     341\label{sec:selection}

     344
    351345%You can copy one scantable to another with the \cmd{copy} function.
    352346
     
    404398from the RPFITS file when reading the data. The values stored in the
    405399RPFITS file are not always correct and so there is a function
    406 \cmd{set\_restfreq} to set the rest frequencies.
     400\cmd{set\_restfreq} to set the rest frequencies for the currently
     401selected data.
    407402
    408403For each integration, there is a rest-frequency per IF (the rest
     
    410405There are a few ways to set the rest frequencies with this function.
    411406
    412 If you specify just one rest frequency, then it is selected for the
    413 specified source and IF and added to the list of rest frequencies.
    414 
    415 \begin{verbatim}
    416   # Select for specified source/IF
    417   ASAP> scans.set_restfreqs(freqs=1.667359e9, source='NGC253', theif=0)
    418 
    419   # Select for all sources and IFs
     407If you specify just one rest frequency, then it is set for all IF.
     408
     409\begin{verbatim}
     410  # Set all IFs
    420411  ASAP> scans.set_restfreqs(freqs=1.667359e9)
    421412\end{verbatim}
    422413
    423 
    424 If you specify a list of frequencies, then it must be of length the
    425 number of IFs.  Regardless of the source, the rest frequency will be set
    426 for each IF to the corresponding value in the provided list.  The
    427 internally stored list of rest frequencies will be replaced by this
    428 list.
    429 
     414If set a rest frequency for each IF, specify a list of frequencies (of
     415length the number of IFs).  Regardless of the source, the rest
     416frequency will be set for each IF to the corresponding value in the
     417provided list.
    430418
    431419\begin{verbatim}
     
    435423\end{verbatim}
    436424
     425{\em Currently this is not implemented}
     426
    437427In both of the above modes, you can also specify the rest frequencies via
    438428names in a known list rather than by their values.
     
    441431
    442432\begin{verbatim}
    443   ASAP> scans.lines()                 # Print list of known lines
    444   ASAP> scans.set_restfreqs(lines=['OH1665','OH1667'])
    445 \end{verbatim}

    447 
    448 \subsection{Data Selection}
    449 
    450 \index{Scantable!data selection}Data selection is currently fairly limited. This
    451 will be improved in the future.
    452 
    453 
    454 \subsubsection{Cursor}
    455 
    456 \index{Scantable!cursor}Generally the user will want to run functions
    457 on all rows in a scantable. This allows very fast reduction of
    458 data. There are situations when functions should only operate on
    459 specific elements of the spectra. This is handled by the scantable
    460 cursor, which allows the user to select a single beam, IF and
    461 polarisation combination.
    462 
    463 Example :
    464 
    465 \begin{verbatim}
    466   ASAP> scans.set_cursor(0,2,1)      # beam, IF, pol
    467   ASAP> scans.smooth(allaxes=F)      # in situ by default or .aipsrc
    468 \end{verbatim}
    469 
    470 \subsubsection{Row number}
    471 
    472 \index{Scantable!row selection}Most functions work on all rows of a
    473 scan table. Exceptions are the fitter and plotter. If you wish to only
    474 operate on a selected set of scantable rows, use the \cmd{get\_scan}
    475 function to copy the rows into a new scantable.
    476 
    477 \subsubsection{Allaxes}
    478 
    479 \index{allaxes}\index{Scantable!allaxes}Many functions have an
    480 \cmd{allaxes} option which controls whether the function will operate
    481 on all elements within a scantable row, or just those selected with
    482 the current cursor. The default is taken from the users {\tt .asaprc}
    483 file.

     503\index{Scantable!management}During processing it is possible to create
     504a large number of scan tables. These all consume memory, so it is best
     505to periodically remove unneeded scan tables. Use \cmd{list\_scans} to

    577547when reading data into ASAP, the reader object should be used.  This
    578 has the option of only reading in a range of integrations and does not
    579 perform any scan averaging of the data, allowing analysis of the
    580 individual integrations.  Note that due to limitation of the RPFITS
    581 library, only one reader object can be open at one time reading RPFITS
    582 files.  To read multiple RPFITS files, the old reader must be
    583 destroyed before the new file is opened.  However, multiple readers
    584 can be created and attached to SDFITS files.

    619 
    620 \subsection{Separate reference and source observations}
    621 
    622 \index{Quotient spectra}Most data from ATNF observatories
    623 distinguishes on and off source data using the file name. This makes
    624 it easy to create two scantables with the source and reference
    625 data. As long as there was exactly one reference observation for each
    626 on source observation for following method will work.
    627 
    628 For Mopra and Parkes data:
    629 \begin{verbatim}
    630   ASAP> r = scans.get_scan('*_R')
    631   ASAP> s = scans.get_scan('*_S')
    632 \end{verbatim}
    633 
    634 For Tidbinbilla data
    635 \begin{verbatim}
    636   ASAP> r = scans.get_scan('*_[ew]')
    637   ASAP> s = scans.get_scan('*_[^ew]')
    638 \end{verbatim}
    639 
    640 \subsection{Make the quotient spectra}
    641 
    642 Use the quotient function
    643 
    644 \begin{verbatim}
    645   ASAP> q = s.quotient(r)
    646 \end{verbatim}
    647 
    648 This uses the rows in scantable \cmd{r} as reference spectra for the
    649 rows in scantable \cmd{s}. Scantable \cmd{r} must have either 1 row
    650 (which is applied to all rows in \cmd{s}) or both scantables must have
    651 the same number of rows. By default the quotient spectra is calculated
    652 to preserve continuum emission. If you wish to remove the continuum
    653 contribution, use the \cmd{preserve} argument:
    654 
    655 \begin{verbatim}
    656   ASAP> q = s.quotient(r, preserve=True)
    657 \end{verbatim}

    864839
    865 \cmd{freq\_align} has two modes of operations controlled by the
    866 \cmd{perif} argument. By default it will align each source and freqid
    867 separately. This is needed for scan tables containing multiple
    868 sources. However if scan-based Doppler tracking has been made at the
    869 observatory, each row will have a different freqid. In these cases run
    870 with \cmd{perif=True} and all rows of a source will be aligned to the
    871 same frame. In general \cmd{perif=True} will be needed for most
    872 observations as Doppler tracking of some form is made at Parkes, Tid
    873 and Mopra.

    1025 \cmd{set\_cursor} function is used to select a subset of the data. The

    12101181
    1211 {\em Currently the receiver position angle is not read from the RPFITS
    1212 file and a position angle of zero is assumed. This severely hampers
    1213 correct handling of polarimetry. In the future we aim to define a
    1214 general framework and populate the RPFITS files with the data required
    1215 for transparent polarimetric calibration.}
    1216 
    12171182\index{Polarisation!calibration}It is possible that there is a phase
    12181183offset between polarisation which will effect the phase of the cross
     
    12301195
    12311196A correction for the receiver parallactic angle may need to be made,
    1232 either because of how it is mounted or if parallactifiying had to track
    1233 at 90 degrees rather than 0. Use \cmd{rotate\_linpolphase} to correct
    1234 the position angle. Running this function twice results in the sum of
    1235 the corrections being applied because it is applied in-situ.
    1236 
    1237 \begin{verbatim}
    1238   ASAP> scans.rotate_linpolphase(-20) # Degrees; correct for receiver mounting
    1239 
    1240   # Receiver was tracking 90 degrees rather than 0
    1241   ASAP> scans.rotate_linpolphase(90)
     1197generally because of how it is mounted. Use \cmd{rotate\_linpolphase}
     1198to correct the position angle. Running this function twice results in
     1199the sum of the corrections being applied because it is applied
     1200in-situ.
     1201
     1202\begin{verbatim}
     1203  ASAP> scans.rotate_linpolphase(-45) # Degrees; correct for receiver mounting
     1204\end{verbatim}
     1205
     1206If the sign of the complex correlation is wrong (this can happen
     1207depending on the correlator configuration), use \cmd{invert\_phase} to
     1208change take the complex conjugate of the complex correlation
     1209term. This is always performed in-situ.
     1210
     1211\begin{verbatim}
     1212  ASAP> scans.invert_phase()
     1213\end{verbatim}
     1214
     1215Depending on how the correlator is configured, ``BA'' may be
     1216correlated insead of ``AB''. Use \cmd{swap\_linears} to correct for
     1217this problem:
     1218
