General Description

We are looking for a distant (~20kpc) stellar stream. Because of the uncertainty
 in the exact location, the fields to be imaged are spread over a large area. The
 finding charts do not show any particular objects of interest, since the stars we
 are looking for are spread over a large part of the sky. Because of the distance
 to the stream, deep photometry is needed. Due to the execution time limit of 1 hour
 for OB's we had to divide the exposures for each pointing over 2 separate OB's.
It is essential that both OB's are completed for a target, since the data from 1
 OB will not suffice to detect the stars we are looking for.

Critical Observing Condition Constraints

Deep photometry is needed in both B and R, meaning that dark time and
 good seeing are necessary.
Because star-galaxy separation will be important near our limiting magnitudes, good
 seeing is extra advantageous.

Time-Critical Aspects

```
There are no time-critical aspects.

Special Execution Requirements

Because we need to go very deep in both B and R, the exposures for each
 pointing had to be divided over 2 separate OB's. For Pointing 1, the exposures are
 in the OB's fld1_BR-1 and fld1_BR-2. The data from 1 OB will not be deep enough
 for our purposes! 
Preference should therefore be given to completing the OB's of 1 target before going
 to the next target.
