Historical measurements of the sensitivity parameter for
Q band filters: Q1 (17.7 um), Q2 (18.7 um), and Q3 (19.5 um).  For each
filter the data are sorted by the pixel-field-of-view: 0.075 arcsec/pixel (SF)
and 0.127 arcsec/pixel (IF). 
Sensitivity is determined by observing a standard star and
estimating the limiting flux expected in 1 hour
"on-source" integration of a point-source detected with S/N of
10. It is given in units of mJy at 10 sigma in 1 hr.
        
       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
