Restricted Imaging mode

This format provides all imaging capabilities of FULL IMAGING, but provides limited spectral resolution (8 channels) and timing resolution (1/8 s for the count rates and up to 32 s for images). It is may be used when the source is too bright (exceeds 120 cts/s) and the full information can't be transmitted to the Earth. In this case raw data with spatial information are written to the JMXi-REST-RAW data structure, and count rates data are written to JMXi-RATE-RAW see details in Tables , . As we loose the time information during the accumulation time the events in the packets are ranked according the position of the triggered pixel (all the pixels have some conventional number in accordance of their position). Note that again only the position of the event with the lowest position number is transmitted (you can find it in JMXi-RATE-PRW) and for all others in TM only the relative positions are given. Pre-Processing calculates the absolute position and add it to the data structure.

Column Name	Description
REST_PHA	Pulse height of the event
DELTA_POS	Delta position number of the event
RAWX	X location of the event (calculated by PreProcessing)
RAWY	Y location of the event (calculated by PreProcessing)
