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

19Trace Addressing
20----------------
21
22Traces are numbered from bottom upward.  A list of traces is specified
23by a list of trace numbers separated by comma or hypen.  Examples:
24   DEL 3          ! deletes 3rd trace
25        DEL 1,4        ! deletes 1st and 4th trace
26   DEL 1-3        ! deletes first 3 traces
27   DEL 1-3,7-9    ! deletes traces 1,2,3,7,8,9
28        DEL ALL        ! deletes all traces

32Some Commands
33-------------
34
35
36  > basic commands ------------------------------------------------------------
37
38
39- start SH from C-shell
40   SH
41
42- open graphics window
43   XOPEN;;              on X-Window system
44
45- exiting from SH
46   QUIT
47
48- help
49   HELP                 directory of (almost all) available commands
50   HELP/KEY             directory with brief description
51   HELP/CALL            directory with calling syntax
52   HELP <cmd>           more detailed help on command <cmd>, example: HELP HELP
53
54- read commands for waveform data
55        READ                 reads from q-files (SH private format)
56        READS                reads from Mini-SEED files (only Steim1 data records)
57        READGSE              reads GSE1 or GSE2 files
58        READAH               reads AH file (if implemented)
59        READA                read ASCII file
60
61- redraw display
62   RD                   redraws display
63   NR                   disables automatic redrawing (re-enable with RD)
64
65- set & delete time windows
66   STW                  set time window
67   DTW                  delete time window
68
69- pick time position on traces
70   TIME                 gives absolute and relative time, also difference
71                        time to last pick, exit with "E"-key
72
73- delete traces
74   DEL <list>           deletes all traces of <list>
75
76- shift traces
77   SHIFT <list> <time>  shift all traces in <list> by <time> seconds
78   SHIFT ALL TIME_AL    shift traces according to their position in absolute time
79   TRESET               sets time-origin to zero for all traces
80
81
82- trace amplitudes
83    NORM AF             default setting.  Traces are normalized to the maximum value
84                        of all traces on the display
85    NORM SF             all traces are displayed with the same amplitude
86    ZOOM <list> <f>     all traces in <list> are amplified by a factor of <f>
87                        this is independent from the NORM command
88- hardcopy
89   HC                   creates PostScript file and sends it to laser printer
90                        print command can be changed with CHANGE_PRN
91                        default print command is: "lpr -Plw %s"
92                        %s is replaced by the actual filename
93   TITLE <n> <t>        puts a title line on the display
94

96
97   > filtering commands ------------------------------------------------------------
98
99
100
101- filtering traces (FFT filters)
102   FILI F <filter>      read in filter file (contains poles and zeroes)
103   FILTER F <list>      filters list of traces
104
105- filtering traces (recursive filters)
106   FILI R <filter>      read in filter file (contains poles and zeroes)
107   FILTER R <list>      filters list of traces
108
109
110
111   > 3-component commands ------------------------------------------------------
112
113
114
115- particle motion diagrams
116   PMSTART <wdwsize>    opens separate window of size <wdwsize> x <wdwsize> cm.
117   PM/MWDW <list> <wd>  particle motion diagrams of N pairs of traces given by
118                        2N elements in <list>.  <wd> is width of time window.
119   PM3 <wd>             abbreviation of PM/MWDW 2,1,3,2,3,1 <wd>
120                        if 3 traces are on the display, same for 6 and 9 traces
121   PMEND                closes PM window
122                        Before using the PM command, set an appropriate time window
123                        with the STW command.
124
125- find azimuth & angle of incidence
126   MDIR <list> *        computes angles according to selected time window.  <list> must
127                        have 2 or 3 elements
128
129- trace rotation
130   ROT3 <list> <a> <i>  3-dim rotation of traces by azimuth <a> and angle of
131                        incidence <i>.  <list> must have 3 elements (Z,N,E).
132   ROTAZ <list> <a>     2-dim azimuth rotation.  <list> must have 2 elements (N,E).
133   ROTINCI <list> <i>   2-dim incidence rotation.  <list> must have 2 elements (Z,R).

138
139
140
141- location of events
142   LOCATE               computes azimuth and slowness for picked phase
143                        exit with "E"-key
144                        Traces MUST have the correct position in time !!!
145                        ensure with the two commands:
146                           SET ALL T-ORIGIN 0.  (or 'TRESET')
147                           SHIFT ALL TIME_AL
148
149- beaming of traces
150   BEAM <list> <a> <s>  shifts traces to align a phase coming from an azimuth of <a>
151                        and a slowness of <s>.
152                        Traces MUST have the correct position in time !!!  (see above)
153
154- summing of traces
155   SUM <list>           sums all traces specified in <list>
