138Release Version 2.0 [2006-04-28]
139
140* Major rework of internal data representation. Now supports IFs with
141 different number of spectral channels. This has minimal effect on the
142 user interface.
143* Creation of a "selector" object used for data selection. Allow slicing of
144 data in beam, IF, polarisation as well as selection via header values
145 (e.g. Tsys). set_cursor is now invalid use set_selection instead.
146* Scantables can be merged
147* scantable.lines() has been removed. Set rest frequencies by value
148 (This will change in 2.1)
149* Multiple data files (e.g. rpf) can be read into a single scantable
150* Polarmetric infrastructure improved to support most observing styles
151 (linear feeds only)
152* ability to convert to/store as Stokes
153* Plotter can now only plot from a single scantable (use merge if necessary)
154* ASCII (text) spectral output changed to be more usable
155* Can change the source position coordinate frame
156* Bug fixes
157* auto_quotient is doing "closest in time reference"
158* option auto-align in velocity when using average_time
159* flagging on a per channel base
160
161
162(Release 1.2.2)

169* Request: Log meesage on auto_quotient()
170* Bug Fix: plotter -set_mode("s","i").
171* Bug fix: plotter -autoscale abcissa limits from all spectra for stacking.
172
173Release Version 1.2.1 [2005-12-06]
174
175* scantable.recalc_azel - recalcualte azimuth and elevation based on

177 cursor not honoured in _plot_time
178
