To be updated! PHI observational modes have changed recently |
Description
PHI science mode 0 is the nominal mode of PHI. However, with the default parameter values (1min cadence and no binning) it generates that much TM that it cannot all be downloaded. Only 9 hours of Mode 0 fit in PHI's orbital allocation. The parameters can be adjusted though to lower resolution or cadence.
This mode can be run either with the Full Disk Telescope (FDT) or with the High Resolution Telescope (HRT), each projecting onto the same camera plane.
Parameters
TBC if anyCadence and binning.

EPS observations:
PHI_FDT_NOM_0 with parameters CADENCE=60 COMPR=2 IC=10 BLOS=10 VLOS=10 GAMMA=8 FI=8
=> PHI_DATARATE = 1607780 [bits/sec] (is automatically calculated from values above)
