[IO] Problem reading Livetime in AXAS D #816

Closed vasole closed 3 years ago

vasole commented 3 years ago
The displayed Live Time is NOT the live time of the energy filter, rather it is a measurement of time that
the triggering filter remained under threshold. This measurement, along with the number of times the
threshold was crossed, or Fast Peaks, is used to calculate the input count rate.

ICR = Fast Peaks / Live Time
The Live Time of the energy filter is not displayed in software, but can be calculated according to:
Energy filter Live Time = Real Time ۰ OCR / ICR
The Dead Time percentage is displayed in software, calculated as:
Dead Time = 1 – OCR/ICR

It seems it is locale dependent. There are files with a "," as decimal point that are properly read and files with a "." as decimal point that are not properly read.
