Historical values of the conversion factor from imaging standard star
observations using the pre-upgrade detector.
Only data taken with the PAH1 filter are selected. The plot is separated
into small-field (SF) pixel field of view (0.075 arcsec/pixel) and
intermediate-field (IF) pixel field of view (0.127 arcsec/pixel).
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
