This plot

This parameter is determined from an overscan-subtracted calibration lamp exposure in LSS mode (taken with the template FORS2_lss_tec_flatLampcheck). The total signal is integrated and normalized by the exposure time and the total number of original CCD pixels (keeping into account possible binning). More information can be found in the plot tutorial. The setup of the lamp check is G300V, GG435 and 1arcsec slit.

  • FFB12 Monitoring the lamp flux of the two blue low brightness halogen lamps FlatBlue+1 and FlatBlue+2. These lamps are used to generate imaging screen flats.
  • FFB34 Monitoring the lamp flux of the two high brightness blue halogen lamps FlatBlue+3 and FlatBlue+4. These lamps are used to generate spectroscopic flats in blue (G300V, G600B) spectroscopic setups.
  • FFR34 Monitoring the lamp flux of the two red halogen lamps FlatRed+3 and FlatRed+4. These lamps are used to generate spectroscopic flats in red spectroscopic setups.
 
General information

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

If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.

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
