32 CCC Variable Type Declarations:
34 Integer*4 trk2_id ! Track ID number
35 Integer*4 trk2_px_sec ! px sector number
36 Integer*4 trk2_py_sec ! py sector number
37 Integer*4 trk2_pz_sec ! pz sector number
38 Integer*4 trk2_sector ! unique sector ID number
39 Integer*4 trk2_flag ! normally=0,if 1 indicates track assigned
40 CCC ! to sector with too many tracks, if = 1
41 CCC ! then track is not used. See /sec_trk2_map/
42 Integer*4 trk2_out_flag ! flag indicating track in/out of accept.
43 CCC ! non-zero for track pushed out of accept.
