Time series of X-ray source RXJ0806. The goal is to image it in
R and I at five epochs. The read-out mode is ABCD,2x2,high
(70.D-0652A.01.WAV).

There is one single OB for each epoch (long OBs approved with
70.D-0652A.02.WAV). As found out when trying to execute the first OB,
though, p2pp severely underestimates the execution time of this
programme and it is not possible to take both of the filters for each
epoch in the same night.  The revised strategy, agreed upon by Andreas
and the PI, is to split the filters in two consecutive nights,
i.e. the R in the first and the I in the second. The second part of
the OB will be executed in the second night even if the constraints
are violated (as it would be if the OB is executed in one night). If
the weather will not allow the execution of the second part in the
second night, the first part will not be repeated, and the second part
executed asap in the given time windows.

Standard star Rubin 152 should be observed right before and after the
science OB in the filter used for it. The OBs for it are provided by
the user. Please check that the standard is not saturated and, in
case, repeat the OB with the correct exposure time (approved by
Fernando Comeron).


TIME CONSTRAINTS:
    1. the first OB should be executed between 8 and 12 December;
    2. the second *has* to be executed the night after the first,
otherwise the whole programme is useless.
    3. 30+-7 days from the execution of the second;
    4. 30+-10 days from the execution of the third;
    5. 30+-10 days from the execution of the fourth;

In case the time constraints cannot be met, please send a ticket to
usd-help and I'll contact the PI (see README).


CALIBRATIONS:

     1. as mentioned above, OBs for standard star Rubin 152 are
provided for observations right before and right after the
science. Please check that it is not saturated and, in case, repeat
the OB with the correct exposure time (approved by Fernando Comeron).
 
     2. skyflat OBs provided for ABCD,2x2,high. Please enter the
coordinates of an appropriate field (approved by Gautier Mathys).

     3. OBs for bias frames also provided.
