6.5 Event list structure in the RGS Spectroscopy Mode

The event list for the RGS Spectroscopy Mode consists of 2 extensions:

• 1 PRIMARY extension, which contains no data

• 1 EVENTS extension, which contains all events, which have passed the non-destructive filters of the reduction procedures/algorithms

A short description of the column in the EVENTS extension is given in Table 33.

Table 33: RGS Spectroscopy Mode event list columns. The placeholders $xy$ are readout node ($x=$0-1) and CCD number ($y=$1-9).
