This plot

Measurements of the sensitivity parameter for several N 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
