All FITS files have the Data-Type encoded within the file name. The Level 0 Spectropolarimeter data are available in two forms. Each 12 hour time slice of data contained thousands of raw spectropolarimeter scans. The spectropolarimetry data are archived in FITS format. Level 1 data products include calibrated spectra and polarizations.
Some objects have multiple pointings.
Calibrations of instrumental polarimetric efficiency, residual polarization, position angle registration, and flux sensitivity were performed by a combination of preflight laboratory measures and in-flight standard star observations. The ZOD was an intensified RCA 320x512 two-dimensional CCD array. The array was uncooled and typically read out every second. No calibrations have been applied to the ZOD images and thus it is Level 0 data. The individual ZOD images are archived in FITS format.
