CbmMvdDigi::CbmMvdDigi ( const CbmMvdRawDigi & rhs,
float pixelSizeX = 0.003024,
float pixelSizeY = 0.002688 )

Conversion Constructor from CbmMvdRawDigi Three limitations make the conversion not 1:1 in all cases: 1) No charge field in MvdRawDigi => Hard-set to 10000 to avoid threshold effect later 2) Potential loss of precision in time conversion from uint64_t to double 3) Narrowing for the frame number field from uint64 to signed int32 => Max value 2147483647 (caught by Fatal)

Default values for pixel sizes taken from core/detectors/mvd/SensorDataSheets/CbmMvdMimosis.cxx Reasoning: 1) Sensor type selected only in CbmMvdGeoHandler.h, for each geometry 2) Type initialized to CbmMvdSensorTyp::MIMOSA26 for CbmMvdGeoHandler in constructor 3) Type static and initialized to CbmMvdSensorTyp::MIMOSIS in beginning of CbmMvdDetector implementation file 4) THEN CbmMvdGeoHandler type FORCED to CbmMvdDetector one in CbmMvdDetector::Instance => If I undertood call sequence right, right now SensorDataSheets instances can only be Mimosis type (PAL, 17/07/2025)

Conversion to CbmMvdRawDigi Three limitations make the conversion not 1:1 in all cases: 1) No charge field in MvdRawDigi => Information lost 2) Potential loss of precision in time conversion from double to uint64_t 3) Narrowing for the frame number field from uint64 to signed int32 => Max value 2147483647 (caught by Fatal)

Protect a bit the conversion back and forth double <=> uint32_t for the time variable Upper limit probably from double side around 53b for worst OSes (cpp std for double) Tested up to 98765432142 ns > 98 s => should be OK for any TS length storage limits to 4294967295 ns > 4.294 s => should be OK for any reasonnable TS length but users may go for it!

Observed in setup_sis100_electron.C with MVD geometry v20d_tr: (by adding a printout in the CbmMvdSensor constructor) "sensor ID" numbers up to 287 for station_S3_1/quadrant_S3_3/sensor_27 => Should be less or similar order of magnitude in all other geometries (especially CFV) => Need to map this into 9 bits => CbmMvdAddress: 9 bits size for combination of Station + SideUD + SideLR + SideTB + Ladder + Sensor

◆ GetAdcCharge()

int32_t CbmMvdDigi::GetAdcCharge ( int32_t adcDynamic,
int32_t adcOffset,
int32_t adcBits ) const

adcOffset is the minimum value of the analogue signal adcDynamic is the difference between the max and min values of the full scale measurement range adcBits is the number of bits used to encode the analogue signal

Exemple: If full scale measurement range is from 15 to 20 Volts adcDynamic is the difference 20 - 15 = 5 adcOffset = 15
