60 |
|
---|
61 | Release Version 2.0 [2006-04-28]
|
---|
62 |
|
---|
63 | * Major rework of internal data representation. Now supports IFs with
|
---|
64 | different number of spectral channels. This has minimal effect on the
|
---|
65 | user interface.
|
---|
66 | * Creation of a "selector" object used for data selection. Allow slicing of
|
---|
67 | data in beam, IF, polarisation as well as selection via header values
|
---|
68 | (e.g. Tsys). set_cursor is now invalid use set_selection instead.
|
---|
69 | * Scantables can be merged
|
---|
70 | * scantable.lines() has been removed. Set rest frequencies by value
|
---|
71 | (This will change in 2.1)
|
---|
72 | * Multiple data files (e.g. rpf) can be read into a single scantable
|
---|
73 | * Polarmetric infrastructure improved to support most observing styles
|
---|
74 | (linear feeds only)
|
---|
75 | * ability to convert to/store as Stokes
|
---|
76 | * Plotter can now only plot from a single scantable (use merge if necessary)
|
---|
77 | * ASCII (text) spectral output changed to be more usable
|
---|
78 | * Can change the source position coordinate frame
|
---|
79 | * Bug fixes
|
---|
80 | * auto_quotient is doing "closest in time reference"
|
---|
81 | * option auto-align in velocity when using average_time
|
---|
82 | * flagging on a per channel base
|
---|
83 |
|
---|
84 |
|
---|
85 | (Release 1.2.2)
|
---|
86 |
|
---|
87 | * channel based flagging
|
---|
88 | * Added get_elevation, azimuth and parangle
|
---|
89 | * Added swap_lineas & invert_phase
|
---|
90 | * added allaxes arg to poly_baseline
|
---|
91 | * Request: added pager throuput for history and summary
|
---|
92 | * Request: Log meesage on auto_quotient()
|
---|
93 | * Bug Fix: plotter -set_mode("s","i").
|
---|
94 | * Bug fix: plotter -autoscale abcissa limits from all spectra for stacking.

---|
96 | Release Version 1.2.1 [2005-12-06]
|
---|
97 |
