## Older Bug corrections

This section contains the list of bugs corrected much longer ago...

1. Corrected 28-Jun-2021 magenta`UV_SHIFT` bug correction for "false" mosaics (ID and MOFF columns)
2. Corrected 28-Jun-2021 magenta`UV_SORT` bug correction for magenta`/FILE` option
3. Discovered and Corrected 27-Oct-2021 magenta`MAP_INTEGRATE` lead to wrong units and noise level.
4. Discovered and Corrected 04-Apr-2021 magenta`MULTISCALE` was using an incorrect convergence strategy since years... Results were sub-optimal, and convergence was unduly slow.
5. Discovered and Corrected 31-Jan-2021 magenta`UV_MAP /RANGE` was producing a wrong velocity/frequency axis since 11-Dec-2020. (a line of code had disappeared).
6. Discovered and Corrected 10-Dec-2020 magenta`MODEL` after magenta`UV_FIT` was ending with an undue error (bug present since 2-Jun-202
7. corrected 8-Dec-2020 Mosaic offsets were not accounted for properly since 19-Jun-2019. The reason was a misplaced exclamation mark that transformed a key instruction into a comment in the code file. Anomalous behaviour of the Mosaic mode were reported end of November, and a test case isolated on Dec 7 for analysis, leading a prompt correction.
8. corrected 26-Oct-2020 Several bugs in magenta`UV_MERGE` made it fail on some (usually large) data files, sometimes depending on the order in which they were given (discovered 15-Oct-2020).
9. corrected 14-Sep-2020 Incorrect transfer of self-calibration solution in magenta`APPLY` and magenta`SELFCAL`APPLY on some UV data set from ALMA.
10. corrected 11-Sep-2020 magenta`KEPLER` was off by 1 pixel.
11. corrected 11-Sep-2020 Blanking was not updated in magenta`MASK APPLY`
12. magenta`UV_SHORT /REMOVE` does not properly delete the SHORT% variable in some cases, in particular if command magenta`XY_SHORT` is (or has been) used (discovered 15-Feb-2020, still pending, difficult to reproduce).
13. corrected 10-Jul-2020 [rgb]1,0,0IMAGER occasionally crashed after a sequence of magenta`UV_MAP /CONT` and magenta`UV_RESTORE` commands, because of a map size mismatch. This size mismatch occured when the baseline min-max of the UV data set are inconsistent with the UV data. (discovered 07-Jul-2020).
14. corrected 10-Jun-2020 magenta`KEPLER` does not handle blue`KEPLER_X0` and blue`KEPLER_Y0` properly.
15. corrected 20-May-2020 magenta`FITS` fails on large (300 GBytes..) UVFITS files. (discovered 15-Feb-2020).
16. corrected 19-Mar-2020 magenta`MODEL /MINVAL` threshold was erroneously transformed between Jy/beam and K.
17. corrected 10-Mar-2020 magenta`MAP_RESAMPLE` may crash on some combination of values (discovered 10-Mar-2020).
18. corrected 10-Mar-2020 magenta`VIEW` may fails the blue`RANGE` is non zero and the 3rd axis increment is negative.
19. corrected 05-Mar-2020 magenta`UV_MAP` fails after magenta`UV_RESIDUAL` and magenta`SELECT UV_RESIDUAL` if the initial UV data set was not sorted in XY.
20. corrected 05-Mar-2020 magenta`MULTI` with non-zero value for blue`CLEAN_NITER` did not set up properly the number of components (it finds 0). magenta`SHOW CCT` and magenta`UV_RESTORE` could not be used after.
