22 * The AliHLTPHOSPeakfinder class is the class for extracting the basic signal parameters
23 * "timing" and "energy" from the PHOS raw data. Physical data will for a given readout channel be
24 * a sequense of ADC digitized 10 bit integer values, however for performance reasons all values used in
25 * calculation is of type double.

42 * Extraction of timing and energy using Crude estimate.
43 * The. The parameters "start" and "length" defines a sub array of the data array
44 * that will be used for the the fit. If start+length must not exeed the total length
45 * of the Data array. "start" must be chosen as close as possible to t0.
46 * The baseline must also be subtracted. .
47 * "index + length" must not exeed the length of the data array set in the constructor.
48 * @param start the start index of the subarray of the data array.
49 * @param length the number of samples to use starting from index
