Known Issues affecting the Cycle 8 2021 release of the ALMA Observing Tool

The following table lists those issues which are known to affect the Cycle 8 2021 version of the Observing Tool. This will be updated to denote whether an issue has been fixed and whether this fix has made it into an updated release.

C1_032 Leaving the OT open for days at a time can cause an error upon saving. Saving to another file, closing the OT and re-opening produces a "ZLIB input stream" error i.e. the project is unreadable. This issue is yet to be satisfactorily characterised.
C2_009 Placing spectral windows that are exactly as far apart as they can possibly be can cause an error, the text of which is also misleading.
C6_001 The OT's mosaicing algorithm will not allow an even number of pointings along a single row. A custom mosaic may be used instead.
C8_001 The time estimate dialogue for VLBI and Phased Array Science Goals is not enforcing the three-hour minimum. However, the correct time is shown on the Cover Sheet and will be used by the Proposal Handling Team.
C8_002 When setting the hour of a multiple visit using the time-constraint interface, it may not be possible to select certain values and attempting to do so may cause the OT to freeze. There is no known workaround at present.
C8_003 Sources with different velocities may bring up a validation error relating to 'tuning groups'. Small changes to the source velocity may solve the problem. The first source typically seems to be the problem.
C8_004 For a "simultaneous" 12-m + ACA proposal, the Cover Sheet will show TP time even if the TP Array is not required. However, TP Time will not be charged to the project.
