38Release 2.2.0 [2007-05-02]
39
40* fix for losing flags in average_time
41* changed asap_update_data to contact ATNF ftp server directly
42* Documentation updates
43* changed to use casacore instead of aips++
44* auto_quotient uses on/off pair detection by default, 'time' the old mode can also
45 be accessed

54

56
57* fix for Ticket #88 - numpy masks
58* better TAB completion for ipython (handles quotes, don't list private members)
59* Fix for Ticket #81 = scanatble.stats output as list
60* ticket #64 - speed up of auto_poly_baseline
61* fix for ticket #89 - export of IF sub-selections
62* fix for Ticket #83 - export to ms2 crashed asap
63* added file suffix support for name.rpf.1 etc.
64
65Release Version 2.1.0 [2006-09-11]
66
67* Processing of Multibeam MX data
68* Line Catalogs for both plotting and setting rest frequencies
69* median averaging
70* support of circular polarisations
71* binaries for fedora (core 3/5), debian, ubuntu, OSX (ppc,intel)
72* text/arrow/line annonations for plotter
73* export of fit parameters to text file
74* disk based scantables for large data sets
75* re-introduced custom quotients
76* fixed major fitter bug
77* fft flagging
78* full support for MOPS data
79
80Release Version 2.0 [2006-04-28]
81
82* Major rework of internal data representation. Now supports IFs with
83 different number of spectral channels. This has minimal effect on the
84 user interface.
85* Creation of a "selector" object used for data selection. Allow slicing of
86 data in beam, IF, polarisation as well as selection via header values
87 (e.g. Tsys). set_cursor is now invalid use set_selection instead.
88* Scantables can be merged
89* scantable.lines() has been removed. Set rest frequencies by value
90 (This will change in 2.1)
91* Multiple data files (e.g. rpf) can be read into a single scantable
92* Polarmetric infrastructure improved to support most observing styles
93 (linear feeds only)
94* ability to convert to/store as Stokes
95* Plotter can now only plot from a single scantable (use merge if necessary)
96* ASCII (text) spectral output changed to be more usable
97* Can change the source position coordinate frame
98* Bug fixes
99* auto_quotient is doing "closest in time reference"
100* option auto-align in velocity when using average_time
101* flagging on a per channel base
102
103
104(Release 1.2.2)
105
106* channel based flagging
107* Added get_elevation, azimuth and parangle
108* Added swap_lineas & invert_phase
109* added allaxes arg to poly_baseline
110* Request: added pager throuput for history and summary
111* Request: Log meesage on auto_quotient()
112* Bug Fix: plotter -set_mode("s","i").
113* Bug fix: plotter -autoscale abcissa limits from all spectra for stacking.
114
115Release Version 1.2.1 [2005-12-06]
116
117* scantable.recalc_azel - recalcualte azimuth and elevation based on
118* pointing Bug fix: plotter - set_layout got overwritten byt plot; row
119 cursor not honoured in _plot_time
120
121
122Release Version 1.2 [2005-11-30]
123
124Code changes
125------------
126* frequency switching: scantable.freq_switch()
127* get a list of sourcenames: scantable.get_sourcename()
128* build quotients from matched _S/_R pairs or 1*_R/n*_S automatically
129* plotting control: plotter.set_colors(), plotter.set_linestyles(),
130 plotter.set_linewidth() all also via .asaprc parameters
131* non-interactive (non-GUI) plotting
132* ASAP Online (Mopra) Monitor web interface (mini pipeline)
133* user control of multi-panel: plotter.set_layout()
134* histogram plotting: part of linestyles
135* plugins: via ~/.asap/userfuncs.py
136* plotter panel control: rcParams['plotter.ganged']
137* usability: reworked the whole asap startup scripts, now all user adjustable
138 through ~/.asap/
139
140Todos/pending
141--------------
142* documentation update: should be finished by 2005-11-25
143* cookbook
144* release 1.2: 2005-11-30

147-----------------------------------------------------
148* asap logging, which can be turned on and off through .asaprc/rcParams
149 (from asapmon)
150* Data container v2 design study and document ( moved from cycle II )
