System Parameters




At Herstmonceux we only observe and keep single photon data. This is
controlled
in the first place in real time while observing and reduces the amount
of multi-photon data to a minimum. Any multi-photon data we do get is
then rejected at the reduction stage.

However with a single photon regime it means the size of the satellite array will play a significant part in some of the parameters that come from the reductions. We have used two of these, RMS and Peak-LEHM, as quality control parameters in our reduction process. More information on satellite signatures can be found here.

We have archived all the results from our reduction process and have used these to arrive at the current limits for RMS and Peak-LEHM. The histograms for each satellite for RMS and Peak-LEHM along with the currently adopted limits for these two parameters are linked below. Data outside these limits is then stopped from being sent out automatically. If after further investigation it is decided that the data is good it will be released.
