Instrument efficiency

Following is the plot of the latest efficiency measurement. The efficiency curves for each order are superimposed.
Agreement with the HARPS Exposure Time Calculator is within 10%.

The text file with the average order efficiencies for the last measurement is available here .
The efficiency archive can be searched here

Efficiency measurements are taken during a photometric or a clear night.
The meteo plot archive can be searched to verify the conditions of the night.
