This plot

After the wavelength calibration is obtained from an LSS arc lamp exposure, the wavelength corresponding to the central CCD pixel is calculated. The values trended here are for the red sensitive MIT detector, the 300V grism with no filter and a slit width of 0.29".

DB Name: fors2_lss_wave
TPL.ID: FORS2_lss_cal_daycalib
QC1 DB parameter: central_wlen

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
