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 - @c fPedestal, @c 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). - @c fVA1MipRange The dymamic MIP range of the VA1_ALICE pre-amplifier chip - @c fAltroChannelSize The largest number plus one that can be stored in one channel in one time step in the ALTRO ADC chip. - @c 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. @ingroup FMD_base */ class AliFMDParameters : public TNamed { public: /** Singleton access @return single to */ static AliFMDParameters* Instance(); /** Initialize the manager.
