Tiled Table Compression Convention
-
Description:
A convention for compressing FITS binary tables and storing the compressed
byte stream in a variable-length array column in a
FITS binary table. Optionally, the table may be divided
into tiles each containing equal-sized blocks of rows that are compressed
together. The current
implementation supports the GZIP and RICE lossless compression
algorithms. The
fpack
FITS file compression utility supports this table compression convention.
The
fpack
Users Guide contains useful general information and tips regarding data compression.
