C- Purpose and Methods : IT FINDS THE NUMBER OF LAYERS (RPIANO) IN WHICH |
| 5 |
C- THERE IS A DETECTED ENERGY BETWEEN EINF AND ESUP . FOR EXAMPLE IF |
| 6 |
C- EINF = 2.5 mip AND ESUP = 10 mip WE INDENTIFY PARTICLE WITH A |
| 7 |
C- CHARACTERISTIC AS ALPHA AT MINIMUM . |
| 8 |
C- QQQQ IS THE TRUNCATED MEAN OF THE DETECTED ENERGY OF THE BARICENTRA OF THE |
| 9 |
C- DEFINED LAYERS . |
| 10 |
C- NTOT GIVES THE NUMBER OF LAYERS WITH DETECTED ENERGY ALONG THE TRACK |
| 11 |
C- DEFINED BY THE TRACKING SYSTEM . WE SAY THAT IS ALONG THE TRACK IF THE |
| 12 |
C- CLUSTER IS INSIDE A RADIUS OF 4 STRIPS BY THE POSITION DEFINED BY THE |
| 13 |
C- TRACKING SYSTEM . |
| 14 |
C- INDICE IS THE NUMBER OF CLUSTERS BESIDES THAT ALONG THE TRACK THAT ARE |
| 15 |
C- MORE THAN 4 STRIPS FAR AWAY BY THE TRACK . |
| 16 |
C- |

C- Created 9-FEB-1994 MIRKO BOEZIO |
| 22 |
C- Modified 28-APR-1994 MIRKO BOEZIO . IF ISTRISCIA IS NEGATIVE AND GREATER |
| 23 |
C- THAN NX THAN NN IS EQUAL 1 . |
| 24 |
C- Modified 8-JUL-1994 MIRKO BOEZIO . CORRECTED AN ERROR ON THE DEFINITION |
| 25 |
C- OF ISTRISCIA . |
| 26 |
C- Modified 14-DEC-1994 MIRKO BOEZIO . THE TRACK IS DEFINED BY THE |
| 27 |
C- TRACKING SYSTEM THROUGH IBAR AND BAR . |
