EXOSAT CMA Images for Each Pointing
Listed in IVOA Registry (Virtual Observatory)
This database table contains the images from two EXOSAT LE telescopes with the channel multiplier array (CMA) detectors in the focal plane.
Description
The CMA/telescope combination covers the 0.05-2.5 keV energy range with a field of view of 2 degrees and an on-axis angular resolution of 24 arc seconds (HEW). The detectors had no intrinsic spectral capabilities; however, different filters were used to make broad band measurements.
The most commonly used were Thin Lexan (number 7), Aluminum-Parylene (number 6) and Boron (number 8). An image was generated for each filter used during an observation. This Browse table was created in March 1995 and updated in October 2003.
