This plot

This plot shows the measured angle of highest polarimetry (P_THETA) of the high polarimetric standard star minus the tabulated angle: qc_THETA_offset. Only V-band values are tabulated for the high polarized standard stars. Trending plots for the R and I band assume that the real (but not tabulated) R and I band polarimetric values are those of the V band. Not all polarimetric standard stars of the catalogue have an entry for the angle. All values are given in degrees.

For the non-polarized standard stars, the angle is not defined.  


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
