- 18-Mar-2022 Add the
CLEAN /RESTART capability

BEAM_STEP = 1
after this, so far.
- 13-Dec-2021 Implement a fast, reliable version of "statcont"
through the
MAP_CONTINUUM command (run time
secs
for a 28 Gbyte data set on a 64-core machine)
- 13-Dec-2021 Globally revised the Robust weighting scheme. Speed
up by huge amount for large (> 10 MegaVis) number of visibilities.
UV data sorting not required anymore.
- 08-Dec-2021 Change the CASA - GILDAS interface. Use pure-Python
scripts and put them in the $HOME/.casa directory to have
a CASA-version independent solution.
- 07-Dec-2021 A missing initialization was causing
UV_RESTORE
to use the slow mode on some compiler versions.
- 06-Dec-2021 Speed up (by a factor 5-10) the Natural weighting scheme
when there is only 1 channel.
- 19-Nov-2021 Create the
VIEWER program, that only contains
the
DISPLAY\ language.
- 19-Nov-2021 Expand the
COMMAND ? Key mechanism
to many commands.
- 18-Nov-2021 Add the
STATISTIC /UPDATE and
FIT /JVM_FACTOR
commands
Changes in Version 3.0
- 31-Oct-2021 Introduce new
DISPLAY\ language. Move commands
CATALOG,
COLOR,
FIND,
EXPLORE,
INSPECT_3D,
SHOW,
STATISTIC, and
VIEW from their initial languages to this one.
- Improvements in control variables of
SHOW and related commands (e.g.
allow unit of contours to be specified).
Changes up to Version 2.8 dated of Jan 31, 2021
- 17-Jun-2021 Add
SPECIFY FREQUENCIES command for VLA data
- 01-Jun-2021 Allow MULTISCALE Clean on Mosaics, better
FIT command.
- 14-Dec-2020
SPECTRAL_CLEAN command
- 31-Jan-2020 Add
CCT_CLEAN command
- 13-Nov-2020 Add
MAP_SMOOTH command
- 26-Oct-2020 Add
UV_SMOOTH command
- 11-Sep-2020 Add
KEPLER /MASK command for Mask creation
- 03-Sep-2020 Better behaviour of command
UV_TIME
- 01-Sep-2020 Improve
FIT command for Mosaics
Changes since Version 2.5 of Feb 27th, 2020, and older ones.
- 13-Nov-2020 Speed-up the
UV_RESTORE command.
- 30-Jul-2020 Miscellaneous improvements in the
KEPLER command
- 26-May-2020 Implementation of the
UV_DETECT command,
that encapsulates all actions needed for matched filtering in UV
plane.
- 14-May-2020 Proper implementation of the
UV_CORRRELATE command,
that performs matched filtering in the UV plane
- 13-May-2020
MODEL defines the
UV_MODEL variable
- 25-Mar-2020 Implementation of the
KEPLER command,
that allows optimal detection of spectral lines in Keplerian disks,
and estimates of radial profiles.
- 19-Mar-2020 Proper implementation of the
MODEL command,
with the
MODEL /MODE option and several channels.
- 11-Mar-2020 Command EXPLORE added to language BUNDLES
- 10-Mar-2020 CASA to GILDAS interface
The casagildas() tool has been totally re-written in pure Python
to avoid issues with incompatible releases of Fortran compilers and
Python between CASA and GILDAS
- 27-Feb-2020
UV_SHORT now allows to use images with non-circular
beams as short spacings data. Such images can be, for example,
an ACA image to be combined with ALMA data.
- 24-Feb-2020 imager-linedb.sic script converted to
Python 2 and 3 compatible syntax
- 21-Feb-2020
UV_MAP was crashing on Mosaic in Robust
weighting. Linked to a missing (although optional !) argument
to call doweig, despite the interface was used.
- 18-Feb-2020
3D size was incorrectly set by
UV_MAP on "huge" file (1200 x 1200 x 3840).
- 14-Feb-2020
Normalize message colours.
- 14-Feb-2020 Suppress blanking when not needed
- 13-Feb-2020 Make
UV_MERGE compliant with its Help:
allow to merge Line data sets in Continuum mode.
- 10-Feb-2020
SLICE command changes.
The SLICE buffer had to be renamed to SLICED, as "slice()" is a
built-in Python method. The axis starts now from the closest point to
(0,0), leading to more intuitive slices.
- 06-Feb-2020
MAP_COMPRESS syntax was incorrectly handled.
The HELP MAP_COMPRESS is still unclear, however.
- 18-Dec-2019
VIEW CCT optimized by coding the component compression after
a
MULTI.
- 17-Dec-2019
SELFCAL optimization (was using slow mode
in
UV_RESTORE by default).
- 27-Nov-2019
UV_CHECK /FILE implemented.
- 27-Nov-2019
UV_TIME /FILE implemented.
- 27-Nov-2019
UV_SHIFT /FILE implemented.
- 20-Nov-2019 Make sure
UV_PREVIEW also works for 1 channel.
