Calibration Access and Data Handbook

Description

The files describe the x-ray effective area and vignetting function of each of the three mirror modules vs field angle and energy. Vignetting by the RGA is not taken into account. The files will each consist of a header and 2 table sections.

• The first table section provides the on-axis effective area as a function of energy between 0.1 to 20 keV in variable step of 0.1 keV to 0.001 keV close to Au absorption edges. This table is used by the CCF access layer to interpolate the on-axis effective area of one mirror module to any energy.

• The second table has 11 different lines for 11 different energies ranging from 100 eV to 15000 eV. Each line provide a set of 27 vignetting factors for off-axis angle ranging from 0 degree to 0.26 degrees per step of 0.01 degree.
