50 /** @brief This class is a singleton that handles various parameters
52 This class reads from the Conditions DB to get the various
53 parameters, which code can then request from here. In that way,
54 all code uses the same data, and the interface is consistent.
56 Some of the parameter managed are
57 - @c fPedestal, @c fPedestalWidth
58 Mean and width of the pedestal. The pedestal is simulated
59 by a Guassian, but derived classes my override MakePedestal
60 to simulate it differently (or pick it up from a database).
62 The dymamic MIP range of the VA1_ALICE pre-amplifier chip
63 - @c fAltroChannelSize
64 The largest number plus one that can be stored in one
65 channel in one time step in the ALTRO ADC chip.
67 How many times the ALTRO ADC chip samples the VA1_ALICE
68 pre-amplifier signal. The VA1_ALICE chip is read-out at
69 10MHz, while it's possible to drive the ALTRO chip at
70 25MHz. That means, that the ALTRO chip can have time to
71 sample each VA1_ALICE signal up to 2 times. Although it's
72 not certain this feature will be used in the production,
73 we'd like have the option, and so it should be reflected in
