This plot

Trending plot for photometric zeropoints.

Photometric standard star fields are typically only measured when they are needed to calibrate science observations in clear or photometric nights. There may be more than one measurement per filter and per night if the science observations require photometric conditions. The zeropoints plotted on the Health Check pages are averages for each night of the zeropoints from the individual measurements.

The plotted values have been converted from ADU to electrons. Please note that downloaded zeropoints from the database are in ADU. The difference to the plotted values is 2.5 * log10(CONAD).

WARNING: Zeropoints have been computed using constant extinction coefficients and zero color terms, with the main purpose of instrument and site performance monitoring. Though they are reasonably precise, they are not suitable for accurate photometric calibrations.

The FULL plot has M1 coating marked with blue vertical lines, M1 washing with cyan lines (since 2010 only).

Template ID: img_cal_Photom. Pipeline recipes: vmimstandard (individual pointing) / vmimcalphot (averaging).  


General information

Click on any of the plots to see a close-up version.

The latest date is indicated on top of the plot.

If configured,

  • data points belonging to the latest date are specially marked
  • 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
