XIS configurations

The different XIS discriminators and thresholds are coded in the filename with a character. This is derived from values written in the HK file. These values are used to define a specific configuration, to which a single alphabetic character is assigned, and are written in header keywords of the cleaned event file. The following tables gives the relation between the filename character and the keywords written in the header of the cleaned event file.

where :

• ADHST and ADHEND are keywords which content give the horizontal start and end addresses of the area discrimination for each of the A, B, C, D segments of the CCD.
• ADVST and ADEND are keywords which content give the vertical start and end addresses of the area discrimination for each of the A, B, C, D segments of the CCD.
• DSCINOT is a flag to indicate if the area discriminator is in or out for each of the A, B, C, D segments of the CCD.

where :

• GDSC is a keyword which has four flags one for different grade type to indicate if they are disable or enable. The grade types are trail, lead, single or other.
• EVTLOW and EVTUP are keywords which content give the lower and upper event threshold for each of the A,B,C,D segments of the CCD.

• AREADISC is a flag to indicate if the area discriminator is disable or enable for each of the A, B, C, D segments of the CCD.

• GRADEDIS is a flag to indicate if the grade discriminator is disable or enable for each of the A, B, C, D segments of the CCD.
