Remarks
method value unit method value
1 QC1DB no none   mag none  8 ext_coeff this | last_yr | all Frame extinction values from FORS2 STD_IMA data for b_HIGH. Values for num_stars <3 suppressed.
2 QC1DB no none   mag none  8 ext_coeff this | last_yr | all same, for filter v_HIGH

3 QC1DB no none   NONE none  8 airmass this | last_yr | all Airmass for values in plot 1. 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.
3 QC1DB no none   NONE none  0 mjd_obs   green bar: night has been classified 'S' (photometrically stable) or 'Sb' (photometric at begin but no more data later); red bar: 'N' (not stable); black bar: 'U' (unknown, no low-high-airmass pair taken); all data apply to the filter above
4 QC1DB no none   NONE none  8 airmass this | last_yr | all same, for filter v_HIGH

This plot

This plot displays a closeup view of the current last 10 days of extinction measurements with FORS2 standard star fields. It contains the pipeline results for the extinction, with the instrumental zeropoint being fixed (read from a static table). Check out the extinction report for the full record of existing data. The bottom panel displays the airmass of the contributing standard star fields, with the stability flag for the given night color-coded. Only data for chip 1 are displayed. This plot helps to monitor the execution of the calibration plan for photometric nights. One can clearly see the inital low-high-airmass pair if acquired. We also mark 'S'/'Sb' nights by a green bar, 'N' nights in red, and 'U' nights in black.

More information can be found on the plot tutorial page.  


General information

Click on any of the plots to see a close-up version. The latest date is indicated on top of the plot, data points belonging to that date are specially marked.

If configured,

  • statistical averages are indicated by a solid line, and thresholds by broken lines
  • outliers are marked by a red asterisk. They are defined as data points outside the threshold lines
  • "aliens" (= data points outside the plot Y limits) are marked by a red arrow ( or )
  • you can download the data for each parameter set if the 'Data downloads' link shows up
