a - Particles (protons) from PIN detectors due to SAA passage.

b - Orbital position of CORONAS at each time.

c - Electron particle environment of the satellite as derived from so-called „rubbish” PHA bins (0 and 31). Brighter colours correspond to larger particle fluxes.

d - Earth map in projection where equal are longitude zones crossed by S/C in each DGI.

e - Proportionality band on the RESIK Channel #3 vs GOES 1 - 8 Å flux plot, where spectra are assumed to be of good quality, solar origin.

f - Measurements taken during favourable environmental conditions i.e. low background during S/C day (in green).

g - Measurements taken during unfavourable times i.e. S/C nights or high particle background emission or in the third order mode (in black) (see Legend „Higher Order” for more info).

h - The HV on detector B changed from 1389 V to 1419 V.

i - Data gap for detector A indicated as dark gray band.

j - Data gap for detector A indicated as d

k - Crystal temperature indicator. Darker green represents ~10oC, purple ~40oC (see temperature bar).

l - Detectors’ High Voltage indicator. Changing colours represent actualvoltage settings see colour boxes.
