This plot

Measurements of the conversion factor from imaging standard star observations. Several N band filters are shown. Note that starting with P95 only small-field (SF) observations with 0.0453 arcsec/pixel are offered.

The conversion factor describes the conversion between ADU and Jy. It is computed as: F(tot.observed) / F(model) [ADU/Jy], where F corresponds to flux and F(model) is the model predicted flux of the standard star from a catalog.  


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
