Detailed Description

This class is a singleton that handles various parameters of the FMD detectors. This class reads from the Conditions DB to get the various parameters, which code can then request from here. In that way, all code uses the same data, and the interface is consistent.

Some of the parameter managed are

  • fPedestal, fPedestalWidth Mean and width of the pedestal. The pedestal is simulated by a Guassian, but derived classes my override MakePedestal to simulate it differently (or pick it up from a database).
  • fVA1MipRange The dymamic MIP range of the VA1_ALICE pre-amplifier chip
  • fAltroChannelSize The largest number plus one that can be stored in one channel in one time step in the ALTRO ADC chip.
  • fSampleRate How many times the ALTRO ADC chip samples the VA1_ALICE pre-amplifier signal. The VA1_ALICE chip is read-out at 10MHz, while it's possible to drive the ALTRO chip at 25MHz. That means, that the ALTRO chip can have time to sample each VA1_ALICE signal up to 2 times. Although it's not certain this feature will be used in the production, we'd like have the option, and so it should be reflected in the code.

UShort_t AliFMDParameters::Init ( AliFMDPreprocessor pp,
Bool_t  forceReInit = kFALSE,

)

Initialize the manager. This tries to read the parameters from CDB. If that fails, the class uses the hard-coded parameters.

Parameters

forceReInitForce (re-)initalize flag
whatWhat to initialize
Returns
0 on success, bit mask of failed elements otherwise

Definition at line 175 of file AliFMDParameters.cxx.

UShort_t AliFMDParameters::Init ( const char *  path,
Bool_t  forceReInit = kFALSE,
UInt_t  what = kAll 
)

Initialize the manager. This will try to read some calibrations (sample rate, strip range, gains, pedestals) from local comma separated value (CSV) files in the directory pointed at by path. If they are not found, then they will be retrieved from OCDB as appropriately. Other calibrations are always read from OCDB.

The CSV files should be named as

  • Pedestals: pedsdet_number.csv
  • Gains: gainsdet_number.csv
  • Sample Rate: conditionsdet_number.csv
  • Strip Range: conditionsdet_number.csv

where det_number is the detector number (1, 2, or 3).

Parameters

forceReInitAlways reinitialise
whatWhat calibrations to load.
Returns
0 on success, bit mask of failed elements otherwise

Bool_t AliFMDParameters::IsDead ( UShort_t  detector,
Char_t  ring,
UShort_t  sector,
UShort_t  strip 
) const

Whether the strip is considered dead

Parameters
detectorDetector # (1-3)
ringRing ID ('I' or 'O')
sectorSector number (0-39)
stripStrip number (0-511)
Returns
true if the strip is considered dead, false if it's OK.

void AliFMDParameters::MakeDeadMap ( Float_t  maxNoise = 10,
Float_t  minGain = .1,
Float_t  maxGain = 10 
)

Automatically generate a dead map from the pedestals and gains. A channel is marked as dead of the noise is too high (currently more than 10 ADC counts), or the gain is unreasonable (currently larger than 10, or smaller than 0.1).

The procedure does not overwrite channels previously marked as dead - e.g., channels marked as dead in the calibration loaded from OCDB will continue to be marked as dead. That is, this procedure will never make a channel un-dead.

Parameters
maxNoiseMaximum noise value before a channel is marked as dead.
minGainMinimum value of the calibrated gain before a channel is considered dead.
maxGainMaximum value of the calibrated gain before a channel is considered dead.

void AliFMDParameters::Print ( Option_t *  option = "A") const

Print all parameters.

If option contains an 'A' then everything is printed.

If the option contains the string "FMD" the function will search for detector, ring, sector, and strip numbers to print, in format

*    FMD<detector><ring>[<sector>,<string>] 
* 

The wild card '*' means all of <detector>, <ring>, <sector>, or <strip>.

Parameters
optionOption string
