dcf3a564 | 19 | // TPC cluster error, shape and charge parameterization as function |
20 | // of drift length, and inclination angle // | |
21 | // | |
22 | // Following notation is used in following | |
23 | // Int_t dim 0 - y direction | |
24 | // 1 - z direction | |
25 | // | |
26 | // Int_t type 0 - short pads | |
27 | // 1 - medium pads | |
28 | // 2 - long pads | |
29 | // Float_t z - drift length | |
30 | // | |
d028aade | 31 | // Float_t angle - tangent of inclination angle at given dimension |
dcf3a564 | 32 | // |
33 | // Implemented parameterization | |
34 | // | |
35 | // | |
36 | // 1. Resolution as function of drift length and inclination angle | |
37 | // 1.a) GetError0(Int_t dim, Int_t type, Float_t z, Float_t angle) | |
38 | // Simple error parameterization as derived from analytical formula | |
39 | // only linear term in drift length and angle^2 | |
40 | // The formula is valid only with precission +-5% | |
41 | // Separate parameterization for differnt pad geometry | |
42 | // 1.b) GetError0Par | |
43 | // Parabolic term correction - better precision | |
44 | // | |
45 | // 1.c) GetError1 - JUST FOR Study | |
46 | // Similar to GetError1 | |
47 | // The angular and diffusion effect is scaling with pad length | |
48 | // common parameterization for different pad length | |
49 | // | |
96305e49 | 50 | // 2. Error parameterization using charge |
51 | // 2.a) GetErrorQ | |
52 | // GetError0+ | |
53 | // adding 1/Q component to diffusion and angluar part | |
54 | // 2.b) GetErrorQPar | |
55 | // GetError0Par+ | |
56 | // adding 1/Q component to diffusion and angluar part | |
57 | // 2.c) GetErrorQParScaled - Just for study | |
58 | // One parameterization for all pad shapes | |
59 | // Smaller precission as previous one | |
