VIRCAM news:
On March 6th, 2023, VIRCAM has been decommissioned after 13 years of operations.
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 ↓)
