This plot

The number of counts is used to calculate the transmission of the dispersive elements. Transmission PRISM=(counts PRISM)/(counts OPEN, DIT=15ms). Transmission GRISM=(counts GRISM)/(counts OPEN, DIT=5ms)  

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
