This plot

This is the trending plot for the Daily Grating Position Check (SW-arm)

This plot describes:
1. The x-position of the bright arc line for the setting: SW MR 1.4097.
2. The y-position of the bright arc line.
3. The tilt angle of the bright arc line.
4. The flux of the bright arc line.

A single frame showing only one bright arc line (with some low flux arc lines that are ignored by the recipe) is submitted to the slit recipe to get some basic geometrical QC information. Find more information about ISAAC slit frames here.

 

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 OPSLOG section on top of the page.

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
