Detailed Description

A struct for the fit parameters for a single channel of the pure CsI calorimeter (in the simulation, all calorimeter channels normally use the same set of fit parameters).

For detailed description of the fit algorithm, see ECL-TN-2013-02 (latest version at https://gitlab.desy.de/belle2/documents/ecl-tn-2013-02/-/blob/master/digi.pdf)

◆ double_matrix

typedef double double_matrix[16][2 *m_ndtPure]

Matrix used in shape fit algorithm.

1st index (i): signal sample ID (waveform always contains 15 signal samples) 0 -> special point that represents average pedestal value 1..15 -> signal samples 2nd index (j): tabulated point ID 0 -> point at the ADC sample #i 1..(m_ndtPure-1) -> points to the right of ADC sample #i m_ndtPure..(2*m_ndtPure - 1) -> points to the left of ADC sample #i

◆ fine_array

typedef double fine_array[2 *m_ndtPure]

Array used in shape fit algorithm.

1st index: tabulated point ID 0 -> point at the signal start 1..(m_ndtPure-1) -> points to the right of the signal start m_ndtPure..(2*m_ndtPure - 1) -> points to the left of the signal start sub-array to tabulate signal fit parameters
