4Release 2.3.0 [2009-01-??]
5
6* Ticket #150 fix in casacore for frequency frame conversions
7* Ticket #151 added rc parameter and function set_sourcetype to identify on/off scans
8* Ticket #78/#112 Resolved the issue with random errors occuring under linux for large
9 data files, which corrupted the identifaction of off scans
10* Ticket #149 Fixed the bug causing spectral line search to go into an infinite loop
11 in some rare circumstances
12* Ticket #110 Added export to CLASS readable FITS files
13 scantable.save("myfile.fits", "CLASS")
14* Ticket #142 Fix of the frequency alignment for long observations
15* Ticket #133 allow supression of history in the scantable via rc parameters
16* Ticket #109 source direction for Hobart data
17* Ticket #115 added running median to scantable.(smooth(kernel='rmedian')
18* Ticket #148 opacity correction wasn't applied to TSYS
19* Ticket #135 quotient detection failure for specific source names
20* Ticket #140 NaN values not handled - added scantable.flag_nans to ensure
21 that the NaN are flagged
22* added python iterator access to scantable rows
23* made functions available to directly manipulate spectra
24 scantable.get/set_spectrum
25* upgrade to support ipython >= 0.8.1
26* support gcc-4.3
27* use scons >= 1.1.0
28* update to latest livedata I/O functions
29* add WCS info to the exported text files

32Release 2.2.0 [2007-05-02]
33
34* fix for losing flags in average_time
35* changed asap_update_data to contact ATNF ftp server directly
36* Documentation updates
37* changed to use casacore instead of aips++
38* auto_quotient uses on/off pair detection by default, 'time' the old mode can also
39 be accessed
40* Ticket #107 added function to shift reference pixel
41* Ticket #106 added function to retrieve integration times
42* Ticket #105 added Parkes K-band gain curve

44* Ticket #104/94 fixed segmentation fault for time average if all channels are flagged
45* Ticket #98 AIPSPATH is honoured if set
46* Ticket #101 fixed set_restfreqs not working for IFs not starting at 0
47* Ticket #97 fixed error in opacity calculation
48
49Minor Release 2.1.1 [2006-11-09]
50
51* fix for Ticket #88 - numpy masks
52* better TAB completion for ipython (handles quotes, don't list private members)
53* Fix for Ticket #81 = scanatble.stats output as list
54* ticket #64 - speed up of auto_poly_baseline
55* fix for ticket #89 - export of IF sub-selections
56* fix for Ticket #83 - export to ms2 crashed asap
57* added file suffix support for name.rpf.1 etc.
58
59Release Version 2.1.0 [2006-09-11]
60
61* Processing of Multibeam MX data
62* Line Catalogs for both plotting and setting rest frequencies
63* median averaging
64* support of circular polarisations
65* binaries for fedora (core 3/5), debian, ubuntu, OSX (ppc,intel)
66* text/arrow/line annonations for plotter
67* export of fit parameters to text file
68* disk based scantables for large data sets
69* re-introduced custom quotients
70* fixed major fitter bug
71* fft flagging
72* full support for MOPS data
73
74Release Version 2.0 [2006-04-28]
75
76* Major rework of internal data representation. Now supports IFs with
77 different number of spectral channels. This has minimal effect on the
78 user interface.
79* Creation of a "selector" object used for data selection. Allow slicing of
80 data in beam, IF, polarisation as well as selection via header values
81 (e.g. Tsys). set_cursor is now invalid use set_selection instead.
82* Scantables can be merged
83* scantable.lines() has been removed. Set rest frequencies by value
84 (This will change in 2.1)
85* Multiple data files (e.g. rpf) can be read into a single scantable
86* Polarmetric infrastructure improved to support most observing styles
87 (linear feeds only)
88* ability to convert to/store as Stokes
89* Plotter can now only plot from a single scantable (use merge if necessary)
90* ASCII (text) spectral output changed to be more usable
91* Can change the source position coordinate frame
92* Bug fixes
93* auto_quotient is doing "closest in time reference"
94* option auto-align in velocity when using average_time
95* flagging on a per channel base
96
97
98(Release 1.2.2)
99
100* channel based flagging
101* Added get_elevation, azimuth and parangle
102* Added swap_lineas & invert_phase
103* added allaxes arg to poly_baseline
104* Request: added pager throuput for history and summary
105* Request: Log meesage on auto_quotient()
106* Bug Fix: plotter -set_mode("s","i").
107* Bug fix: plotter -autoscale abcissa limits from all spectra for stacking.
108
109Release Version 1.2.1 [2005-12-06]
110
111* scantable.recalc_azel - recalcualte azimuth and elevation based on
112* pointing Bug fix: plotter - set_layout got overwritten byt plot; row
113 cursor not honoured in _plot_time
114
115
116Release Version 1.2 [2005-11-30]
117
118Code changes
119------------
120* frequency switching: scantable.freq_switch()
121* get a list of sourcenames: scantable.get_sourcename()
122* build quotients from matched _S/_R pairs or 1*_R/n*_S automatically
123* plotting control: plotter.set_colors(), plotter.set_linestyles(),
124 plotter.set_linewidth() all also via .asaprc parameters
125* non-interactive (non-GUI) plotting
126* ASAP Online (Mopra) Monitor web interface (mini pipeline)
127* user control of multi-panel: plotter.set_layout()
128* histogram plotting: part of linestyles
129* plugins: via ~/.asap/userfuncs.py
130* plotter panel control: rcParams['plotter.ganged']
131* usability: reworked the whole asap startup scripts, now all user adjustable
132 through ~/.asap/
133
134Todos/pending
135--------------
136* documentation update: should be finished by 2005-11-25
137* cookbook

143 (from asapmon)
144* Data container v2 design study and document ( moved from cycle II )
