FITS File for ACIS Contamination

Verification Tests of ACIS Contamination FITS File

Tests of: acisD1999-08-13contamN0001.fits, the ACIS contamination transmission function vs time. The file specification is given in this Interface Control Document

Time and Transmission Data

The plots show 3 curves, one for each of: C-K (white), O-K (light blue), and F-K (green). (CIP and FITS data are overplotted, but only 3 curves are visible since the CIP and FITS data are identical, as they should be.)
Relative thickness trend with time.
Relative thickness vs year.

Transmissivity at fiducial time.
Transmissivity vs wavelength.
