6General Remarks
7---------------
8
9- command line interpreter is not case-sensitive
10- command line consists of command-verb, parameters and qualifiers
11- separation characters are blanks " " or semicolons ";"
12- qualifiers are preceded by a slash.
13- delete scratch files in directory shscratch from time to time

16Some Commands
17-------------
18
19
20- start SH
21   SH
22
23- open graphics window
24   XOPEN;;              on X-Window system
25
26- exiting from SH
27   QUIT
28
29- help  *** BUG on Linux installation ***
30   HELP                 directory of (almost all) available commands
31   HELP HELP            explanation of HELP command
32   HELP/KEY             directory with brief description
33   HELP/CALL            directory with calling syntax
34   HELP <cmd>           detailed help on command <cmd>, example: HELP HELP
35
36- read & write commands
37   READA <filename> [<dt> <length>]
38                        reads data from ASCII files
39   READS <path> <time> <seclength> <stations> <comps> <chan>
40                        reads from Mini-SEED files (special SH subformat)
41   READ <q-file> <list> reads data from q-file (private SH data format)
42   WRITE <q-file> <list>
43                        writes data to q-file
44
45- redraw display
46   RD                   redraws display
47   NR                   disables automatic redrawing (re-enable with RD)
48
49- set & delete time windows
50   STW                  set time window
51   DTW                  delete time window
52
53- pick time position on traces
54   TIME                 gives absolute and relative time, also difference
55                        time to last pick, exit with "E"-key
56
57- delete traces
58   DEL <list>           deletes all traces of <list>
59
60- shift traces
61   SHIFT <list> <time>  shift all traces in <list> by <time> seconds
62   SHIFT ALL TIME_AL    shift traces according to their position in absolute
63                        time
64   T-ALIGN              repositions all traces correct in time
65
66
67- trace amplitudes
68    NORM AF             default setting.  Traces are normalized to the maximum
69                        value of all traces on the display
70    NORM SF             all traces are displayed with the same amplitude
71    ZOOM <list> <f>     all traces in <list> are amplified by a factor of <f>
72                        this is independent from the NORM command
73
74- filtering traces (FFT filters)
75   FILI F <filter>      read in filter file (contains poles and zeroes)
76   FILTER F <list>      filters list of traces
77   MAKEF                calls external program to create filter files
78
79- location of events
80   LOCATE               computes azimuth and slowness for picked phase
81                        exit with "E"-key
82                        Traces MUST have the correct position in time !
83                        ensure with the command T-ALIGN.
84
85- beaming of traces
86   DELAY+SUM <list> <a> <s>
87                        shifts traces to align a phase coming from an azimuth
88                        of <a> and a slowness of <s>.  Traces are aligned
89                        in time automatically before operation.
90
91- summing of traces
92   SUM <list>           sums all traces specified in <list>
93
94- hardcopy
95   PHC;;                creates PostScript file and sends it to laser printer
96   TITLE <n> <t>        puts a title line on the display
97
98- rotation of traces
99   ROTAZ <list> <azim>  rotates horizontal traces to R and T
100
101- particle motion diagrams
102   PMSTART <wdwsize>    opens separate window of size <wdwsize> x <wdwsize> cm.
103   PM/MWDW <list> <wd>  particle motion diagrams of N pairs of traces given by
104                        2N elements in <list>.  <wd> is width of time window.
105   PM3 <wd>             abbreviation of PM/MWDW 2,1,3,2,3,1 <wd>
106                        if 3 traces are on the display, same for 6 and 9 traces
107   PMEND                closes PM window
108                        Before using the PM command, set an appropriate time
109                        window with the STW command.
110
111- utilities
112   DEMEAN <list>        removes mean value
113   TREND <list>         removes linear trend
114   DESPIKE <list> <f>   removes spikes
115   DECIMATE <list> <f>  decimate traces (average deleted samples)
116   CUT <list> <lo> <hi> cuts traces at the specified time bounds
117   MARK <trc> <time>    marks trace (marks can be labelled, see HELP MARK)
118   SYSTEM               access to UNIX shell
119   @                    execute single command case sensitive
