FITS Checksum Proposal
Rob Seaman, William Pence, Arnold Rots
The checksum keywords described here provide an integrity check on the information contained in FITS HDUs. (Header and Data Units are the basic components of FITS files, consisting…
A Tiled-Table Convention for Compressing FITS Binary Tables
William Pence, Rob Seaman, Richard L. White
This document describes a convention for compressing FITS binary tables that is modeled after the FITS tiled-image compression method (White et al. 2009) that has been in use for a…
Tiled Image Convention for Storing Compressed Images in FITS Binary Tables
Richard L. White, Perry Greenfield, William Pence +2
This document describes a convention for compressing n-dimensional images and storing the resulting byte stream in a variable-length column in a FITS binary table. The FITS file st…
Optimal DN encoding for CCD detectors
Robert L. Seaman, Richard L. White, William D. Pence
Image compression has been a frequent topic of presentations at ADASS. Compression is often viewed as just a technique to fit more data into a smaller space. Rather, the packing of…
Lossless Astronomical Image Compression and the Effects of Noise
W. D. Pence, R. Seaman, R. L. White
We compare a variety of lossless image compression methods on a large sample of astronomical images and show how the compression ratios and speeds of the algorithms are affected by…
