34 * calculation is of type double.

50 * The. The parameters "start" and "length" defines a sub array of the data array
51 * that will be used for the the fit. If start+length must not exeed the total length
52 * of the Data array. "start" must be chosen as close as possible to t0.
53 * The baseline must also be subtracted.
54 * The length of "tVector" and "aVector" mus be equal to length.
55 * "index + length" must not exeed the length of the data array set in the constructor.
56 * @param start the start index of the subarray of the data array.
57 * @param length the number of samples to use starting from index
