General Description

The goal is to obtain a spectrum in polarised light of the black hole
 X-ray binary A0620-00. The chosen grism is 150I with filter GG435+81 covering 450-850
 nm. Four 900s exposures are taken with the retarded plate at 0, 22.5, 45 and 67.5
 degree. The linear spectral polarisation will be deduced from the set of four exposures.

Dear Dr. Dubus,

I am happy to inform you that your waiver request to have OB 1.5h long has
been granted. Please note that the usual restriction will apply meaning
that if the conditions degrade in violation of the constraints after the
first hour, the OB will not be repeated.

For your convenience I attach below the copy of the request.
Best regards,

Marina

Special Execution Requirements

PMOS fast acquisition is sufficient for a single target.

Special Calibration Information

Program will require standard calibration i.e.
- PMOS arcs
- PMOS flats (45 degree)
- PMOS polarized standard
- PMOS unpolarized standard
Please ensure these will be available!
