Low, moderate, high long term and high short term solar and geomagenetic activities have the following meanings:
low (F10.7 = F10.7_avg = 65, S10.7 = S10.7_avg = 60, M10.7 = M10.7_avg = 60, A_p = 0)
moderate (F10.7 = F10.7_avg = 140, S10.7 = S10.7_avg = 125, M10.7 = M10.7_avg = 125, A_p = 15)
high long term (F10.7 = F10.7_avg = 250, S10.7 = S10.7_avg = 220, M10.7 = M10.7_avg = 220, A_p = 45)
high short term (F10.7 = 300, F10.7_avg = 250, S10.7 = 235, S10.7_avg = 220, M10.7 = 240, M10.7_avg = 220, A_p = 240)
