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
