source: trunk/doc/CHANGELOG@ 1504

Last change on this file since 1504 was 1497, checked in by Max Voronkov, 16 years ago

fixed #149. The problem was inside getMask method. In some rare circumstances largely when single channel detections are allowed and with spectral averaging enabled, the method failed to flag the lines which have already been detected and went into infinite loop by detecting them again. The condition of leaving the loop (no new lines found) was never satisfied as a result of this.

26
27Release 2.2.0 [2007-05-02]
28
29* fix for losing flags in average_time
30* changed asap_update_data to contact ATNF ftp server directly
31* Documentation updates
32* changed to use casacore instead of aips++
33* auto_quotient uses on/off pair detection by default, 'time' the old mode can also
34 be accessed

43
44Minor Release 2.1.1 [2006-11-09]
45
46* fix for Ticket #88 - numpy masks
47* better TAB completion for ipython (handles quotes, don't list private members)
48* Fix for Ticket #81 = scanatble.stats output as list
49* ticket #64 - speed up of auto_poly_baseline
50* fix for ticket #89 - export of IF sub-selections
51* fix for Ticket #83 - export to ms2 crashed asap
52* added file suffix support for name.rpf.1 etc.
53
54Release Version 2.1.0 [2006-09-11]
55
56* Processing of Multibeam MX data
57* Line Catalogs for both plotting and setting rest frequencies
58* median averaging
59* support of circular polarisations
60* binaries for fedora (core 3/5), debian, ubuntu, OSX (ppc,intel)
61* text/arrow/line annonations for plotter
62* export of fit parameters to text file
63* disk based scantables for large data sets
64* re-introduced custom quotients
65* fixed major fitter bug
66* fft flagging
67* full support for MOPS data
68
69Release Version 2.0 [2006-04-28]
70
71* Major rework of internal data representation. Now supports IFs with
72 different number of spectral channels. This has minimal effect on the
73 user interface.
74* Creation of a "selector" object used for data selection. Allow slicing of
75 data in beam, IF, polarisation as well as selection via header values
76 (e.g. Tsys). set_cursor is now invalid use set_selection instead.
77* Scantables can be merged
78* scantable.lines() has been removed. Set rest frequencies by value
79 (This will change in 2.1)
80* Multiple data files (e.g. rpf) can be read into a single scantable
81* Polarmetric infrastructure improved to support most observing styles
82 (linear feeds only)
83* ability to convert to/store as Stokes
84* Plotter can now only plot from a single scantable (use merge if necessary)
85* ASCII (text) spectral output changed to be more usable
86* Can change the source position coordinate frame
87* Bug fixes
88* auto_quotient is doing "closest in time reference"
89* option auto-align in velocity when using average_time
90* flagging on a per channel base
91
92
93(Release 1.2.2)
94
95* channel based flagging
96* Added get_elevation, azimuth and parangle
97* Added swap_lineas & invert_phase
98* added allaxes arg to poly_baseline
99* Request: added pager throuput for history and summary
100* Request: Log meesage on auto_quotient()
101* Bug Fix: plotter -set_mode("s","i").
102* Bug fix: plotter -autoscale abcissa limits from all spectra for stacking.
103
104Release Version 1.2.1 [2005-12-06]
105
106* scantable.recalc_azel - recalcualte azimuth and elevation based on
107* pointing Bug fix: plotter - set_layout got overwritten byt plot; row
108 cursor not honoured in _plot_time
109
110
111Release Version 1.2 [2005-11-30]
112
113Code changes

115* frequency switching: scantable.freq_switch()
116* get a list of sourcenames: scantable.get_sourcename()
117* build quotients from matched _S/_R pairs or 1*_R/n*_S automatically
118* plotting control: plotter.set_colors(), plotter.set_linestyles(),
119 plotter.set_linewidth() all also via .asaprc parameters
120* non-interactive (non-GUI) plotting
121* ASAP Online (Mopra) Monitor web interface (mini pipeline)

124* plugins: via ~/.asap/userfuncs.py
125* plotter panel control: rcParams['plotter.ganged']
126* usability: reworked the whole asap startup scripts, now all user adjustable
127 through ~/.asap/
128

138 (from asapmon)
139* Data container v2 design study and document ( moved from cycle II )
