This plot

This plot shows the RMS of the world coordinates (RA and DEC) of the source positions identified in photometric standard star product frames when compared to the positions in the 2MASS photometric and astrometric catalogue. In the absence of imperfect correction of the wide field optical distortion of VISTA, uncertainty of the barycenter of the telescope and seeing PSF, refraction and other effects the mininmum RMS that can be achieved is the instrinsic RMS of the 2MASS catalogue. Note that 1 detector pixel corresponds to 0.339 arcsec.  


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
