The EPHIN E-detector developed gradually a noise problem during 1996 and was switched off logically on 1996-305-14.40. Check EPHIN status word >Ephin_Stat< bit 2 (2^2): if set to one: E detector is on, if set to zero, E detector is off. When off, the channels E3000, P41 and H41 show zero intensity, the energy of the next lower channel E1300 is the average of E1300 and E3000, the width of channel E1300 is the sum of the width E1300 and E3000; P25, and H25 are changed accordingly. Note: the KPGS calulates correctly the new fluxes in channels E1300, P25, H25. Only their interpretation needs to be changed by the user. 2. The geometric factor for the counting rate channels can be changed either by ground command or autonomously by detecting high fluxes in the center segment of detector A. Check EPHIN status word >Ephin_Stat<bits 9,10,11,12,13,17,18,19,20,21: if set to one: large geometric factor, if set to zero: small geometric factor. Note: the KPGS software calculates correctly the fluxes. No action needed by the user.

MAST flags: If '0' data is perfect But '1' is advisory to look into 30-sfluxes. PARTIAL '1' signifies thatsome 30-s fluxes were omitted;BAD '1' signifies bad or no data withentries being fill values. ADC_SATsignifies that count data mayhave had saturated values. 'Saturation' only means that the count rate inany or all channels exceeded thecalibration count rate of 10,000/s
If flag is '0' data is perfect; if '1' it is advisable to look into the30-s fluxes: PARTIAL '1' signifiesthat some 30-s data were omitted;BAD '1' signifies bad/absent data,with fill value as the entry;P1HI_SAT '1' signifies that somesaturated values. 'Saturation' simplymeans that the count rates exceededthe calibration counts of 10,000/s.
For all flags 0 means perfect data.But 1 is an advisory to look intothe 30-s flux data: PARTIAL '1' means some 30-s data were eliminated;BAD '1' means bad or no data and entryis a fill value; SSD_SAT '1' means that a small amount of saturatedSSD data is admitted; MCP_SAT '1' signifies that a small amount of saturated MCP data is admitted.So called 'Saturation' simply meansthat the count rates in the SolidState Detectors or the Micro ChannelPlates exceeded the calibrating ratesof 10,000 counts/s during any 30-s.
If entry is '0', data is perfect. But '1' is advisory to look into 30-sflux data: PARTIAL '1' signifies thatsome 30-s values were ignored; BAD '1' signifies bad/no data and entry is afill value.
