This plot

Number of independent wavelengths used in the computation of the mean spectral resolution. The values trended here are for the 300V grism with a slit width of 1.0", INS.MOS.CHECKSUM = 0 (i.e. all slitlets are in the center) and the GG435 order separation filter.  


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
