10. ZIMPOL
Wolfgang Hummel, , QC meeting

11. ZIMPOL (data) Raw data = 2 extensions, 1k x 1k x NDIT cube
Products = 16 extensions 1k x 1k
4 modes: imaging and P1, P2, P3 (rotation modes)
P1: no field derot. (short exposures)
P2: active field derot. (field is fixed, polarisation can drift, long exposures)
P3: pseudo field derot. (combination of P1 and P2).
