a - Log GOES flux level in W/m2 (RESIK flux has been put to scale by subtracting the value of 8.7).
b - Radiation belt passages High Voltage is OFF (HV-off periods are always in dark gray).
c - Spacecraft nights as seen by optical satellite sensor.
d - Minimum and maximum DGI value for a given sequence [s].
f - Flare duration & position (from SOHO EIT).
g - Dump identification (the number of orbit when the data presented were sent to the ground).
h - Orientation of the dispersion planes of RESIK crystals projected on the Sun (heliographic coordinates
i - Levels corresponding to particular GOES X-ray flare classes.
j - GOES fluence in 0.5 - 4 Å (in blue) and 1- 8 Å (in red)- 1 min data.
k - RESIK lightcurve plot for Channel #2 (Ar XVII) denoted in "software" as #0. Points in green denote times when clean RESIK spectra are available. Points in black are rejected from the summed spectra, while points in light brown correspond to periods when the satellite is in the auroral regions emission due to in-situ X-ray emission.
l - Lowest level of the orbital background. Spectra taken during these periods are used in order to subtract the background emission.
