This plot
Trending plots for efficiency (throughput in electrons per photon) measurements with
spectro-phomtometric standard stars.
The overall instrument efficiency is measured with standard star observations
in 5 dedicated settings: 1087.3, 1504.8, 2205.0, 3611.0, and 5050.4 nm
reference wavelength. These plots show the median throughput for chip 3.
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
