1. Planning summary
===================
1.1 General remarks
a) Maintenance gap at ISDC: Pointings 10 to 14 missed (will be recovered in cons)
b) Preprocessing restarted due to a loss of synchronization. Unfortunately, Pointings 16 to 19 failed,
but they will be recovered in consolidated)
c) Pointing 19 missed (no record in AHF)
d) Pointing 39 missed
e) 2019-12-04T18:42: VDM5V ISGRI anomaly. Patch performed by MOC at 20:41.
