Changelog ========= Release 2.3.0 [2009-01-??] * Ticket #149 Fixed the bug causing spectral line search to go into an infinite loop in some rare circumstances * Ticket #110 Added export to CLASS readable FITS files scantable.save("myfile.fits", "CLASS") * Ticket #142 Fix of the frequency alignment for long observations * Ticket #133 allow supression of history in the scantable via rc parameters * Ticket #109 source direction for Hobart data * Ticket #115 added running median to scantable.(smooth(kernel='rmedian') * Ticket #148 opacity correction wasn't applied to TSYS * Ticket #135 quotient detection failure for specific source names * Ticket #140 NaN values not handled - added scantable.flag_nans to ensure that the NaN are flagged * added python iterator access to scantable rows * made functions available to directly manipulate spectra scantable.get/set_spectrum * upgrade to support ipython >= 0.8.1 * support gcc-4.3 * use scons >= 1.1.0 * update to latest livedata I/O functions * add WCS info to the exported text files Release 2.2.0 [2007-05-02] * fix for losing flags in average_time * changed asap_update_data to contact ATNF ftp server directly * Documentation updates * changed to use casacore instead of aips++ * auto_quotient uses on/off pair detection by default, 'time' the old mode can also be accessed * Ticket #107 added function to shift reference pixel * Ticket #106 added function to retrieve integration times * Ticket #105 added Parkes K-band gain curve * Ticket #102 fixed wrong polarisation type in case of 'circular' * Ticket #104/94 fixed segmentation fault for time average if all channels are flagged * Ticket #98 AIPSPATH is honoured if set * Ticket #101 fixed set_restfreqs not working for IFs not starting at 0 * Ticket #97 fixed error in opacity calculation Minor Release 2.1.1 [2006-11-09] * fix for Ticket #88 - numpy masks * better TAB completion for ipython (handles quotes, don't list private members) * Fix for Ticket #81 = scanatble.stats output as list * ticket #64 - speed up of auto_poly_baseline * fix for ticket #89 - export of IF sub-selections * fix for Ticket #83 - export to ms2 crashed asap * added file suffix support for name.rpf.1 etc. Release Version 2.1.0 [2006-09-11] * Processing of Multibeam MX data * Line Catalogs for both plotting and setting rest frequencies * median averaging * support of circular polarisations * binaries for fedora (core 3/5), debian, ubuntu, OSX (ppc,intel) * text/arrow/line annonations for plotter * export of fit parameters to text file * disk based scantables for large data sets * re-introduced custom quotients * fixed major fitter bug * fft flagging * full support for MOPS data Release Version 2.0 [2006-04-28] * Major rework of internal data representation. Now supports IFs with different number of spectral channels. This has minimal effect on the user interface. * Creation of a "selector" object used for data selection. Allow slicing of data in beam, IF, polarisation as well as selection via header values (e.g. Tsys). set_cursor is now invalid use set_selection instead. * Scantables can be merged * scantable.lines() has been removed. Set rest frequencies by value (This will change in 2.1) * Multiple data files (e.g. rpf) can be read into a single scantable * Polarmetric infrastructure improved to support most observing styles (linear feeds only) * ability to convert to/store as Stokes * Plotter can now only plot from a single scantable (use merge if necessary) * ASCII (text) spectral output changed to be more usable * Can change the source position coordinate frame * Bug fixes * auto_quotient is doing "closest in time reference" * option auto-align in velocity when using average_time * flagging on a per channel base (Release 1.2.2) * channel based flagging * Added get_elevation, azimuth and parangle * Added swap_lineas & invert_phase * added allaxes arg to poly_baseline * Request: added pager throuput for history and summary * Request: Log meesage on auto_quotient() * Bug Fix: plotter -set_mode("s","i"). * Bug fix: plotter -autoscale abcissa limits from all spectra for stacking. Release Version 1.2.1 [2005-12-06] * scantable.recalc_azel - recalcualte azimuth and elevation based on * pointing Bug fix: plotter - set_layout got overwritten byt plot; row cursor not honoured in _plot_time Release Version 1.2 [2005-11-30] Code changes ------------ * frequency switching: scantable.freq_switch() * get a list of sourcenames: scantable.get_sourcename() * build quotients from matched _S/_R pairs or 1*_R/n*_S automatically * plotting control: plotter.set_colors(), plotter.set_linestyles(), plotter.set_linewidth() all also via .asaprc parameters * non-interactive (non-GUI) plotting * ASAP Online (Mopra) Monitor web interface (mini pipeline) * user control of multi-panel: plotter.set_layout() * histogram plotting: part of linestyles * plugins: via ~/.asap/userfuncs.py * plotter panel control: rcParams['plotter.ganged'] * usability: reworked the whole asap startup scripts, now all user adjustable through ~/.asap/ Todos/pending -------------- * documentation update: should be finished by 2005-11-25 * cookbook * release 1.2: 2005-11-30 Major non-targets, resulting from requirements/targets ----------------------------------------------------- * asap logging, which can be turned on and off through .asaprc/rcParams (from asapmon) * Data container v2 design study and document ( moved from cycle II ) Not Addressed ------------- (deferred to cycle II, as described in support document) * Flexible data selection * "Merging of spectra" (concatenating scantables) * public defect tracking system
