The OSIRIS Data Reduction Pipeline (DRP) converts raw 2-d images into 3-d datacubes via rectification matrices (recmats). These FITS files are 152 MB each when uncompressed. Here we provide them compressed using Solaris gzip (file sizes range from 30-90 MB).
OSIRIS has changed over time. For some changes, new calibration scans are taken and new recmats are built from these calibration scans. Please note the text in the hyperlinks. The format is YYMMDD_Filter_Scale. The date implied by YYMMDD is the date on which the calibration scans were taken. In most cases you want the latest recmat created with data taken BEFORE your science data. The current recmats in use by OSIRIS correspond to the highest version number. The exception to this is for the 100 mas scale. Some of the earlier 100 mas calibrations scans were saturated. Please download the LATEST rectificaiton matrices for the 100 mas scale.
