Measurements of the sensitivity parameter for the three
Q band filters. Note that starting with
P95 only small-field (SF) observations with 0.0453 arcsec/pixel
are offered.
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
