PICsIT Standard Mode

In this mode the information is accumulated on-board and transmitted to the Earth in a kind of histograms. Spectral-image histograms are written to the Data Structures PICS-SISH-RAW and PICS-SIMH-RAW for single and multiple events correspondingly. These Data Structures represent a three dimensional table with total counts during integration time. The axes of the grid are directed along the following axes: AXIS 1 - Channel number, AXIS 2 - Y position, AXIS 3 - Z position.

Spectral-timing histograms are written to the Data Structure PICS-SPTI-RAW and contain the information on the number of the events accumulated in the up to 8 energy bins during a given time amount, see Table 31

Table 31: Content of PICS-SPTI-RAW Data Structure.
 
Column Name Description
CELL_1 1st cell of the spectrum
CELL_2 2nd cell of the spectrum
CELL_3 3rd cell of the spectrum
CELL_4 4th cell of the spectrum
CELL_5 5th cell of the spectrum
CELL_6 6th cell of the spectrum
CELL_7 7th cell of the spectrum
CELL_8 8th cell of the spectrum
The local on-board time and the channels definitions can be found in the PICS-SPTI-PRW Data Structure.
