The status pages are automatically updated every hour. Note that if a night is flagged as "Transferred by WFAU" it does not mean that it is already available for download from the WSA: there are extra overheads due to ingestion and data curation tasks.

General Information about WFCAM data products
Rice image compression
CASU is using the Rice lossless compression to store both the raw and reduced data. Rice compression is supported by CFITSIO and by DS9 (starting from version 5).
CASU is using the Zenithal Polynomial projection (ZPN) to encode the astrometric calibration in the FITS headers. Although ZPN is part of the FITS standard for WCS encoding, it is not supported by IRAF until the last version. ZPN is instead correctly understood by other software packages like DS9 and Gaia. For more information on how to fix this problem, see the IRAF ZPN Patch document. If you use Terapix software (e.g., SExtractor or Swarp), check out the Terapix Software ZPN howto document to lean about ZPN-related issues.
