extinction |
all (full time range)
| Night extinction values for R_SPEC and detector CCID20-14-5-3 (HC plot: 28 days delay; available since 2012-06). The extinction is only displayed for nights with stable photometric conditions (stable flag is 'S' or 'Sb'). |

ext_coeff |
all (full time range)
| Frame extinction values from STD_IMA data for above filter and chip. Values for num_stars <3 suppressed. These values are derived from single frames, under the assumption of a constant zeropoint. All values are plotted, regardless of 'stable' flag value. |

| Airmass for values in plot 1 (R_SPEC). For nights classified 'S' or 'Sb' there should always be a pair with delta_AIRM > 0.4. Data points per night are connected by a line. |
