Availability of Signal Types and Meaning of Data Values

2-ID-B (*.hdf files):

In this case, the available signal types are Calibrated kHz and Predefined Combinations. Calibrated kHz, however, are not really calibrated kHz but the raw data (Volts from the ADC).

2-ID-E (*.mda) files):

Same as above, except that the physical meaning is not necessarily Volts but whatever the raw data is recorded as (counts for V2F channels, bits for ADC channels from fly scans, Volts for ADC channels from step scans).

Silicon Detector (*.sdt) files:

If ...

• there is no calibration available in the file (parameter is_calibrated = 0), the same holds as above for 2-ID-E files.

• the calibration for the V2F and ADC is available (parameter is_calibrated = 1), the raw data described above is stored in "Raw Integer", and the calibrated V2F and ADC data is available as Calibrated kHz (ADC in mVolts, Sidet and "Nova 2V ref" data from the V2F also mVolts, all other V2F data (clock, ion chambers) in counts).

• the silicon detector calibration is available as well (parameter is_calibrated = 2 or 3), all signal types are available. The calibrated V2F and ADC data are now available as "Raw counts / mVolts" and "Calibrated kHz" holds the calibrated silicon detector data (clock in ms, all other channels same as "raw counts / mVolts").
