hic Calibration Processing History

hic is the processing history file produced by the VMICAL reduction stage. The history file includes a record of which files were processed, values of site-dependent parameters used in the processing, calibration information, a log of GRASP modules called by VMICAL (including time stamps), and reprocessing history.

hiz is the processing history file produced by the GEOMPIPE subsystem of the VMICAL reduction stage. The processing history file includes the date of processing, names of the flat field image and the magnetogram flat field image used, image subsection used, GRFLAT, GEOM, and HGEOM parameters, and the list of QA parameter files generated for this stage.

For data prior to 960801, VMICAL and GEOMPIPE were separate reduction stages. This data will have separate processing history files for the VMICAL and GEOMPIPE stages. Data after this date will have these files combined in the hic file and no separate hiz file will exist.
