|
|
* A TRACK is defined by: |
| 10 |
|
|
* - the measured points associated to it |
| 11 |
|
|
* - their spatial resolution |
| 12 |
|
|
* - the track status vector AL-pha |
| 13 |
|
|
* |
| 14 |
|
|
* This common must be filled when calling mini_2. After the fit, |
| 15 |
|
|
* the initial values of AL-pha (initial guess, for instance from Hough) |
| 16 |
|
|
* are replaced with the minimization result. |
| 17 |
|
|
* |
| 18 |
|
|
* About the measured points: |
| 19 |
|
|
* - a COUPLE defines a point in the space; in this case you should set |
| 20 |
|
|
* |
| 21 |
|
|
* XGOOD = 1 |
| 22 |
|
|
* YGOOD = 1 |
| 23 |
|
|
* XM,YM,ZM = coordinates of the point in cm |
| 24 |
|
|
* RESX = spatial resolution of cl-x |
| 25 |
|
|
* RESY = spatial resolution of cl-y |
| 26 |
|
|
* |
| 27 |
|
|
* - a SINGLET (single cluster x/y) defines a segment AB, parallel to |
| 28 |
|
|
* the x/y strips; in this case you should set, for example in the case |
| 29 |
|
|
* of a cl-x: |
| 30 |
|
|
* |
| 31 |
|
|
* XGOOD = 1 |
| 32 |
|
|
* YGOOD = 0 |
| 33 |
|
|
* ZM = average z coordinate of the segment AB in cm |
| 34 |
|
|
* XM_A,YM_A = coordinates of extreme point A |
| 35 |
|
|
* XM_B,YM_B = coordinates of extreme point B |
| 36 |
|
|
* RESX = spatial resolution of cl-x |
| 37 |
|
|
* |
| 38 |
|
|
* NB!!! ZM must be always initialized, at least with the mechanical positions |
| 39 |
|
|
* |
| 40 |
|
|
* (All the needed quantities for couples and singlets can be evaluated |
| 41 |
|
|
* by means of the routine xyz_PAM) |
