The following keys are used to define a SINFONI telluric standard and PSF star setup:
ins.setup.id [grism/filter] (= S1_J, S2_H, S3_K, or S4_H+K) ins.opti1.name [pixel scale] (= 0.025, 0.1, or 0.25) det.dit (= ANY that match the DIT of the STD or PSF frame)
The following calibrations have a special status with SINFONI:
PSF: The PSF standards are not regular calibrations, but can be explicitly requested by the PI.
If, however, they are obtained, then cal4cal will check that all requisite calibrations needed for their processsing are complete.
