formats, we added station code to the coda message to make it
simpler to export codas along with their picks via export_scn.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
1. TYPE_PICK2K
This message type is created by pick_ew and read by binder, eqproc, eqprelim,
export_scn. The new TYPE_PICK2K message
is a fixed 72 characters long (including a newline, but excluding a
null-terminator).

it was. However, since we're changing formats, we added station code
to the coda message to make it simpler to export codas along with their
picks via export_scn. The TYPE_CODA2K message is a fixed format,
79 characters long (including a newline character, but excluding a
null-terminator).

6. TYPE_HYP2000ARC (barely filled in)
TYPE_HYP2000ARC (completely filled in)
The TYPE_HYP2000ARC messages is output by eqcoda,
read and output by eqverify, hyp2000_mgr (hyp2000), and read by menlo_report,
rsec*, arc2trig, earlybird.
A TYPE_HYP2000ARC message is a fixed-format message and is built of 6
different types of lines in the following sequence:
hypocenter (1. Summary Header Format)
hypocenter shadow (2. Summary Shadow Format)
phase 1 (3. Station Archive Format Year 2000)
phase shadow 1 (4. Station Shadow Format, RTP portion)
...
phase N
phase shadow N
terminator line (5. Event Terminator Format)
terminator shadow (6. Event Terminator Shadow)
For Hyp2000, the "Summary Header Format" and "Station Archive Format" in the
archive message have changed. All other lines in the TYPE_HYP2000ARC message
have the same format as the original TYPE_HINVARC message. A complete
description of the new Hyp2000 formats can be found in Fred Klein's Hypoinverse Manual.

7. TYPE_TRIGLIST2K
This message type is created by trg_assoc, carlsubtrig, arc2trig, and is
read by surf.exe (WaveViewer), trig2disk, ora_trace_save, and maybe some
others. TYPE_TRIGLIST2K is a space-delimited message, where the time fields
have a fixed format. It is composed of an event header line, 3 silly
comment lines, and any number of individual station trigger lines.
Here's an example:
Y2K-compliant TYPE_TRIGLIST2K:
