18 | C. * NUMBV volume numbers * | |
19 | C. * HITS array of values for the elements of current hit * | |
20 | C. * ITRA track number associated to this hit * | |
21 | C. * IHIT output parameter containing the hit number * | |
22 | C. * If IHIT=0 hit has not been stored * | |
23 | C. * * | |
24 | C. * Same action as GSAHIT but in case the physical volume * | |
25 | C. * specified by NUMBV contains already some hit for the * | |
26 | C. * same track, then the routine will sum up the last NHSUM * | |
27 | C. * elements of the hit. * | |
28 | C. * In order to use that routine , no packing must be * | |
29 | C. * specified for these NHSUM last hits. * | |
30 | C. * If NHSUM.LE.0 then GSCHIT is the same as GSAHIT. * | |
