[bananas] BPASS bug, AIPSLetter

[Eric Greisen]

A significant bug in BPASS has been found.  Channel-dependent flagging 
could cause the reference antenna to change in the middle of a spectrum! 
  This led to bad phases in the solution.  It has been repaired in both 
31DEC21 and 31DEC20.

The June 30 issue of the AIPSLetter for 31DEC21 has been released.
See ftp://ftp.aoc.nrao.edu/pub/software/aips/TEXT/PUBL/LET21A.PDF

The shipping numbers for 31DEC21 are down - I do recommend updating your 
installation to the latest version.  But you really should run the MNJ
($HOME/do_daily.<hostname>) on 31DEC20 at the very least.

Stay safe
