| 613 | *     This routine provides the coordinates (in cm) in the PAMELA reference system: | 
| 614 | *       - of the point associated with a COUPLE ---> (xPAM,yPAM,zPAM) | 
| 615 | *       - of the extremes of the segment | 
| 616 | *         associated with a SINGLET ---------------> (xPAM_A,yPAM_A,zPAM_A) | 
| 617 | *                                               ---> (xPAM_B,yPAM_B,zPAM_B) | 
| 618 | * | 
| 619 | *     It also assigns the spatial resolution to the evaluated coordinates, | 
| 620 | *     as a function (in principle) of the multiplicity, the angle, the PFA etc... | 
| 621 | * | 
| 622 | * | 
| 623 | *     To call the routine you must pass the arguments: | 
| 624 | *     icx    - ID of cluster x | 
| 625 | *     icy    - ID of cluster y | 
| 626 | *     sensor - sensor (1,2) | 
| 627 | *     PFAx   - Position Finding Algorithm in x (COG2,ETA2,...) | 
| 628 | *     PFAy   - Position Finding Algorithm in y (COG2,ETA2,...) | 
| 629 | *     angx   - Projected angle in x | 
| 630 | *     angy   - Projected angle in y | 
| 631 | *     bfx    - x-component of magnetci field | 
| 632 | *     bfy    - y-component of magnetic field | 
| 633 | * | 
| 634 | *     --------- COUPLES ------------------------------------------------------- | 
| 635 | *     The couple defines a point in the space. | 
| 636 | *     The coordinates of the point are evaluated as follows: | 
| 637 | *     1 - the corrected coordinates relative to the sensor are evaluated | 
| 638 | *         according to the chosen PFA --> (xi,yi,0) | 
| 639 | *     2 - coordinates are rotated and traslated, according to the aligmnet | 
| 640 | *         parameters, and expressed in the reference system of the mechanical | 
| 641 | *         sensor --> (xrt,yrt,zrt) | 
| 642 | *     3 - coordinates are finally converted to the PAMELA reference system | 
| 643 | *         --> (xPAM,yPAM,zPAM) | 
| 644 | * | 
| 645 | *     --------- SINGLETS ------------------------------------------------------- | 
| 646 | *     Since a coordinate is missing, the singlet defines not a point | 
| 647 | *     in the space but a segment AB (parallel to the strips). | 
| 648 | *     In this case the routine returns the coordinates in the PAMELA reference | 
| 649 | *     system of the two extremes A and B of the segment: | 
| 650 | *         --> (xPAM_A,yPAM_A,zPAM_A) | 
| 651 | *         --> (xPAM_B,yPAM_B,zPAM_B) |
