    00009  *     Revision 1.1  2006/05/19 16:55:02  paulf
    00009  *     first inclusion
    00009  *
    00010  *     Revision 1.6  2000/12/06 17:47:07  lucky
    00011  *     Removed Pph and Sph strings from Hpck, and added Plabel, Slabel, Ponset,
    00012  *     and Sonset. We need these to properly track the onset.
    00013  *
    00014  *     Revision 1.5  2000/09/12 19:07:02  lucky
    00015  *     Defined separate FM fields for S and P picks
    00016  *
    00017  *     Revision 1.4  2000/08/21 19:48:36  lucky
    00018  *     Modified the Hpck structure to be able to handle both P and S
    00019  *     picks at the same time, by specifying time, residual, quality, and phase
    00020  *     remarks separately for P and S picks.
    00021  *
    00022  *     Revision 1.3  2000/06/12 21:34:00  lucky
    00023  *     Changed NO_FLOAT_VAL, NO_INT_VAL, and NO_LONG_VAL to 0.
    00024  *
    00025  *     Revision 1.2  2000/03/30 15:35:30  davidk
    00026  *     Added fields to Hsum and Hpck that contained information neccessary for
    00027  *     orareport, so that the read_arc routines could be used by orareport.
    00028  *
    00029  *     Revision 1.1  2000/02/14 20:05:54  lucky
