## Older Bug corrections

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

1. Corrected 28-Jun-2021 UV_SHIFT bug correction for "false" mosaics (ID and MOFF columns)
2. Corrected 28-Jun-2021 UV_SORT bug correction for /FILE option
3. Discovered and Corrected 27-Oct-2021 MAP_INTEGRATE lead to wrong units and noise level.
4. Discovered and Corrected 04-Apr-2021 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 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 MODEL after 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 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 APPLY and SELFCALAPPLY on some UV data set from ALMA.
10. corrected 11-Sep-2020 KEPLER was off by 1 pixel.
11. corrected 11-Sep-2020 Blanking was not updated in MASK APPLY
12. UV_SHORT /REMOVE does not properly delete the SHORT% variable in some cases, in particular if command XY_SHORT is (or has been) used (discovered 15-Feb-2020, still pending, difficult to reproduce).
13. corrected 10-Jul-2020 IMAGER occasionally crashed after a sequence of UV_MAP /CONT and 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 KEPLER does not handle KEPLER_X0 and KEPLER_Y0 properly.
15. corrected 20-May-2020 FITS fails on large (300 GBytes..) UVFITS files. (discovered 15-Feb-2020).
16. corrected 19-Mar-2020 MODEL /MINVAL threshold was erroneously transformed between Jy/beam and K.
17. corrected 10-Mar-2020 MAP_RESAMPLE may crash on some combination of values (discovered 10-Mar-2020).
18. corrected 10-Mar-2020 VIEW may fails the RANGE is non zero and the 3rd axis increment is negative.
19. corrected 05-Mar-2020 UV_MAP fails after UV_RESIDUAL and SELECT UV_RESIDUAL if the initial UV data set was not sorted in XY.
20. corrected 05-Mar-2020 MULTI with non-zero value for CLEAN_NITER did not set up properly the number of components (it finds 0). SHOW CCT and UV_RESTORE could not be used after.
