VST Data Processing
VST data processing status:
Rice image compression
CASU is using lossless Rice tile compression to store both the raw and reduced data. Rice compression is supported by CFITSIO and by DS9 (starting from version 5). You can use funpack to uncompress the images.
VST has very low astrometric field distortion hence CASU is using a Tangent Plane projection (TAN) to encode the WCS astrometric calibration in the FITS headers.
