- 18-Mar-2022 Add the
CLEAN /RESTART capability
- 10-Mar-2022 Improve dirty beam related commands behaviour: replace
MAP_BEAM_STEPby
BEAM_STEP, use
BEAM_SIZE to specify beam shape.
-
Corrected 09-Mar-2022
CCT_MERGE Concatenation was improper
- 07-Mar-2022 Allow
WRITE BEAM /APPEND in all cases
-
Corrected 07-Mar-2022 Beam size derivation was incorrect when an ANGLE was specified
-
Corrected 08-Feb-2022
UV_RESTORE was not using fixed beam size.
- 08-Feb-2022 Implement the
CLEAN_STOP syntax in
CLEAN
-
Corrected 18-Jan-2022,
Discovered 17-Jan-2022 only SINGLEDISH data was
incorrectly read, probably since 20-Sep-2021 (v1.53 of read.f90). Improper values were thus
used by the
UV_SHORT command.
-
Corrected 12-Jan-2022 Mosaic offsets were improperly computed by command
UV_FIELDS since 29-Jul-2021 (bug reported 10-Jan-2022). The script
@ fits_to_uvt was thus leading to wrong pointing offsets.
- 10-Jan-2022 Implement the
LOAD command in
VIEWER.
-
Corrected 10-Jan-2022 A improper interaction between scripts was causing
strange behaviour when switching between
EXPLORE and
INSPECT_3D commands.
- 07-Jan-2022 Implement
SHOWPV and improve transposed data display.
-
Corrected 06-Jan-2022 The
SIC command DEFINE IMAGE failed on large
FITS files. This prevented
SHOW and
VIEW to work directly from these files.
- 06-Jan-2022 Allow direct
READ of FITS data cubes.
- 03-Jan-2022 Improve syntax of
COMBINE
-
Corrected 18-Dec-2021
UV_TIME produced incorrect results on tables
with different weights per channel (e.g. those produced by
UV_MERGE /MODE CONCATENATE).
- 17-Dec-2021 Improve
UV_CHECK BEAM and
FIT commands.
- 16-Dec-2021 Add the
UV_MERGE /MODE CONCATENATE
command to stitch adjacent or overlapping spectral windows.
Imaging is in general only possible using
BEAM_STEP = 1after this, so far.
- 13-Dec-2021 Implement a fast, reliable version of "statcont"
through the
MAP_CONTINUUM command (run time
\(< 40\)
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.
-
Corrected 13-Dec-2021 Remove occasional infinite loop in
MAP_CONTINUUM
with method GAUSS (discovered 01-Dec-2021)
- 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.
-
Corrected 18-Nov-2021
UV_REWEIGHT syntax bug
- 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).
-
Corrected 28-Jun-2021
UV_SHIFT bug correction for "false" mosaics (ID and MOFF columns)
-
Corrected 28-Jun-2021
UV_SORT bug correction for
/FILE option
- Discovered and
Corrected 27-Oct-2021
MAP_INTEGRATE lead to wrong units
and noise level.
- Discovered and
Corrected 04-Apr-2021
MULTISCALE was using an incorrect convergence
strategy since years... Results were sub-optimal, and convergence was unduly slow.
- 17-Jun-2021 Add
SPECIFY FREQUENCIES command for VLA data
- 01-Jun-2021 Allow MULTISCALE Clean on Mosaics, better
FIT command.
