153Release Version 2.0 [2006-04-28]
154
155* Major rework of internal data representation. Now supports IFs with
156 different number of spectral channels. This has minimal effect on the
157 user interface.
158* Creation of a "selector" object used for data selection. Allow slicing of
159 data in beam, IF, polarisation as well as selection via header values
160 (e.g. Tsys). set_cursor is now invalid use set_selection instead.

163 (This will change in 2.1)
164* Multiple data files (e.g. rpf) can be read into a single scantable
165* Polarmetric infrastructure improved to support most observing styles
166 (linear feeds only)
167* ability to convert to/store as Stokes
168* Plotter can now only plot from a single scantable (use merge if necessary)
169* ASCII (text) spectral output changed to be more usable
170* Can change the source position coordinate frame
171* Bug fixes
172* auto_quotient is doing "closest in time reference"

184* Request: Log meesage on auto_quotient()
185* Bug Fix: plotter -set_mode("s","i").
186* Bug fix: plotter -autoscale abcissa limits from all spectra for stacking.
187
188Release Version 1.2.1 [2005-12-06]
189
190* scantable.recalc_azel - recalcualte azimuth and elevation based on
191* pointing Bug fix: plotter - set_layout got overwritten byt plot; row
192 cursor not honoured in _plot_time
193
194

196
197Code changes
198------------
199* frequency switching: scantable.freq_switch()
200* get a list of sourcenames: scantable.get_sourcename()
201* build quotients from matched _S/_R pairs or 1*_R/n*_S automatically
202* plotting control: plotter.set_colors(), plotter.set_linestyles(),
203 plotter.set_linewidth() all also via .asaprc parameters
204* non-interactive (non-GUI) plotting
205* ASAP Online (Mopra) Monitor web interface (mini pipeline)
206* user control of multi-panel: plotter.set_layout()
207* histogram plotting: part of linestyles
208* plugins: via ~/.asap/userfuncs.py
209* plotter panel control: rcParams['plotter.ganged']
210* usability: reworked the whole asap startup scripts, now all user adjustable
211 through ~/.asap/
212
