163Release Version 2.0 [2006-04-28]
164
165* Major rework of internal data representation. Now supports IFs with
166 different number of spectral channels. This has minimal effect on the
167 user interface.
168* Creation of a "selector" object used for data selection. Allow slicing of
169 data in beam, IF, polarisation as well as selection via header values
170 (e.g. Tsys). set_cursor is now invalid use set_selection instead.

173 (This will change in 2.1)

175* Polarmetric infrastructure improved to support most observing styles
176 (linear feeds only)
177* ability to convert to/store as Stokes
178* Plotter can now only plot from a single scantable (use merge if necessary)
179* ASCII (text) spectral output changed to be more usable
180* Can change the source position coordinate frame
181* Bug fixes
182* auto_quotient is doing "closest in time reference"

196* Bug fix: plotter -autoscale abcissa limits from all spectra for stacking.
197
198Release Version 1.2.1 [2005-12-06]
199
200* scantable.recalc_azel - recalcualte azimuth and elevation based on
201* pointing Bug fix: plotter - set_layout got overwritten byt plot; row
202 cursor not honoured in _plot_time
203
204

209* frequency switching: scantable.freq_switch()
210* get a list of sourcenames: scantable.get_sourcename()
211* build quotients from matched _S/_R pairs or 1*_R/n*_S automatically

213 plotter.set_linewidth() all also via .asaprc parameters
214* non-interactive (non-GUI) plotting
215* ASAP Online (Mopra) Monitor web interface (mini pipeline)

217* histogram plotting: part of linestyles
218* plugins: via ~/.asap/userfuncs.py
219* plotter panel control: rcParams['plotter.ganged']
220* usability: reworked the whole asap startup scripts, now all user adjustable
221 through ~/.asap/
222
