Version History of SH and SHM

23-feb-96 SH-4.0a
first ftp version of SH
26-feb-96 SH-4.0b
removed scan_streams* from $SH_UTIL, new examples for compiler-flags in setup/shsetup
26-mar-96 SH-4.0c

22-may-96 SH-4.0d
included HP-UX version
29-may-96 SH-4.0e

05-jun-96 SH-4.0f
missing compiler switch on HP-UX, fixed Makefile of mapmatrix
16-sep-96 SH-4.0g
fixed bug in array beam routine (mt_locate). Now use geometric center as reference. This bug caused errors in slowness and azimuth for large aperture arrays (GRSN). Slowness and Azimuth output in evt-files now in hundredths.
27-Dec-96 SH-4.0h
Implementation of SH-update scripts via ftp. Renaming of SHN to SH_N.
13-Jan-97 SH-4.0i
Trace display resizeable, text menue for configuring SHM.
22-Jan-97 SH-4.0j
new shmsetup-parameter 'auto_phase'. SHMSETUP continues after unknown item.

After SH-4.0j there are separate lists for SH and SHM:


19-Mar-97 SH-4.0k
GSE2.0 input improved: fixed bug in reading INTV data, GSE2 input can also read GSE1.0 (automatic distinction). Fixed bug in GSE1.0-cmp6 input. 'READGSE' is now obsolete, exists only for compatibility.
28-Apr-97 SH-4.0l
Implemented phase picker of Baer/Kradolfer? (command PICK)
30-May-97 SH-4.0m
Two serious bugs in READGSE2 found and fixed. (1) Amplitudes were wrong if calibration period not equal to 1 in GSE2 files. (2) READGSE2 missed one digit of the milliseconds when reading GSE1 files -> Time error up to 1 sec. (reading GSE2 files with READGSE2 was o.k.)
05-Dec-97 SH-4.0n
command 'reads': Fixed calib=0-bug when reading starts in a gap. Time-axis is not shifted any more in the distance-proportional display.
01-Sep-98 SH-4.0o
Can read mixed MiniSEED of 512-byte and 4096-byte records.
