This is an imaging programme, aimed to detect RR-Lyrae variables in
NGC6822 in V and I passbands.

Due to the angular size of NGC6822, the users observe it in two
different FORS1 fields (F1,F2). In order to have a proper time
resolution, they need to have the OBs executed in three different
nights, possibly consecutive and at least very close to each-other.
OBs belonging to the same night (marked as N1,N2 and N3) have to be
executed consecutively.
This has been authorized, but the user has been warned that the
constraints will be guaranteed during the first hour only.
Execution time is about 4 hours per night.
 
Note that the users ask for the execution of extra photometric standard
stars. They have submitted specific OBs for this within their allocated
time, and they ask to execute these OBs during night N3, at different 
airmasses.
