PMOS of a White Dwarf. The star has a high proper motion, the direction and magnitude of which are indicated in the finding chart. There are 12 identical science OBs. Each consists in two circular and 4 linear polarizations. In order to sample the light curve, no more than two OBs should be executed in the same night. Ideally 6-12 consecutive nights should be used. The user-provided polarized standard should be observed once every FORS1 Service mode run, i.e. not every night a science OB is executed (see the README file). The unpolarized standard just once in the entire P67. In order to save time, the CCD is windowed. Taking this into account, the execution time is smaller than the allocation, no matter what p2pp says.
