Formal changes to use fortran routines in the presampler analysis

1 mocchiut 1.1 SUBROUTINE ELIO(RPIANO,NPIANI,QQQQ,NTOT,INDICE)
2     C----------------------------------------------------------------------
3     C-
4     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-
17     C- Inputs : NPIANI
18     C- Outputs : RPIANO,QQQQ,NTOT,INDICE
19     C- Controls:
20     C-
21     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 .
