j_cor_position

The program works with the data received in Full & Restricted Imaging modes. With the use of the position mapping tables (see Appendix [*]) j_cor_position converts detector positions corrected for microstrip plate irregularities into absolute values.

This component also determines whether there are hotspots on the microstrip plate and flags all the events orginating in hotspot areas so that these events can be ignored by the rest of the science analysis. It also flags dubious events coming from dead anodes, inactive areas around the detector and areas around the calibration areas.

See Appendix [*] for the description of j_correction output.

Name Type Description
COR_gainHist string DOL of the Index Group with gain variation history JMXi-GAIN-CAL-IDX. Empty string automatically takes the value of any IC Gain History DOL.

default: '' ''

     
COR_gainModel integer With this parameter you choose the smoothing model to be applied.

possible values:

-1 (default) Let the algorithm choose between the optimal model to be used (i.e., 4 for JEMX-1 and 3 for JEMX-2).

0 Linear interpolation between gain history values.

1 Fixed gain parameters - obsolete. This value will automatically default to model 2.

2 Exponential gain decay with linear segment immediately after switch. Models the normal time variation of gain slope in a revolution.

3 Non-trigger dependent model.

4 Hardware trigger dependency in the smoothing. If there is no significant trigger variation during the revolution, then the program defaults back to model 3.

default: -1
