This plot

From a wavelength calibrated LSS arc lamp exposure, the mean spectral resolution from all lines in the catalog is computed. Each single spectral resolution is computed as the ratio between the arc lamp line wavelength and its FWHM. The values trended here are for the red sensitive MIT detector, the 300V grism with no filter and a slit width of 0.29".

On 2018-08-28 new pipeline (v.5.3.35) was introduced. The method of calculating spectral resolution changed and the new values are significantly lower.

On 2024-09-01 binning of the LSS_HC_LAMP calibrations was changed from 2x2 to 1x1. This created a jump in the resolution estimates.

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
