This plot

These are the trending plots for the SINFONI QC parameters derived from the LAMP FLATs.

These plots describe:
Day-time FLAT calibrations come in at least five pairs of lamp on/off frames. For each
raw lamp-on frame the corresponding lamp-off frame is subtracted and the median is calculated.
The above lamp efficiencies are the average of these 5 (or more) values.

Median lamp count limits should remain between 4,000 and 10,000 ADU. The lower limit ensures that the flux levels of the flats are sufficiently high for good statistical noise limits, while the upper limit of 10,000 counts should not be exceeded as this can approach the detector's non-linear regime.

1. the median lamp counts in the J-band for the camera scales: 250, 100, and 25 mas
2. the median lamp counts in the H-band for the camera scales: 250, 100, and 25 mas
3. the median lamp counts in the K-band for the camera scales: 250, 100, and 25 mas
4. the median lamp counts in the H+K-band for the camera scales: 250, 100, and 25 mas

General information

Click on any of the plots to see a close-up version.

If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPSLOG section on top of the page.

The latest date is indicated on top of the plot, data points belonging to that date are specially marked.

If configured,

  • 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
