12Simulation filters used by SHM
13------------------------------

17Application of simulation filters to traces read by SHM need preinstalled
18filter files located either in $PWD or in $SH_FILTER.  The filter files
19cannot be created automatically at runtime, because information about
20transfer function of the recording instrument must be supplied somehow.
21Looking for the filter files SHM assumes file names of a defined format:
22
23
24FFT-files: '<rec-instr>_S+<sim-filter>.FLF'
25
26        where    <rec-instr>     Descriptor of the recording instrument.  By default
27                            this is '<station>:<channel>:<comp>'
28            <station>       Station name (examples: 'BFO', 'GEC2')
29            <channel>       2-character SEED channel code (examples: 'BH', 'HH')
30            <comp>          Component (examples: 'Z', 'N')
31            <sim-filter>    Descriptor of simulated instrument.
32                            (examples: 'WOODAND', "G_WWSSN_SP')
33
34recursive files: '<smprate>HZ_<rec-instr>_S+<sim-filter>.FLR'
35
36   where    <smprate>       Integer sample rate in Hz (examples: '20', '40')
37            <rec-instr>     See above
38            <sim-filter>    See above

41All filenames must have uppercase letter only !  Hyphens in filter filenames
42are not supported by SHM.  As an example, a legal filename for an FFT
43simulation filter for WWSSN-LP recorded at station RAR-BH-Z would be
44'RAR:BH:Z_S+WWSSN_LP.FLF'.
45
46Since it is rather inconvenient to have separate filter files for each stream,
47it is possible to combine several streams to a single class name within a
48lookup table.  Class names found in the lookup table replace the individual
49stream names within the filenames.  SHM searches two lookup tables: an internal
50table (implemented in the source code) and an external table in the file
51'$SH_INPUTS/filter_lookup.txt'.  The internal table maps all GRF-BH-streams
52(e.g. GRA1-BH-Z, GRB1-BH-N) to the name 'GRF', all GRSN-BH-streams
53(e.g. BFO-BH-Z, CLZ-BH-E) to the name 'GRSN' and all GERESS-HH-streams
54(e.g. GEA0-HH-Z) to the name 'GERESS'.  The complete internal lookup
55table (status of 12-Jul-1996) is appended to this text.  Due to this lookup
56table the simulation filter for WWSSN_LP on stream BFO-BH-Z is
57'GRSN_S+WWSSN_LP.FLF' instead of 'BFO:BH:Z_S+WWSSN_LP.FLF'.  In the external
58lookup table arbitrary mappings of additional stations can be added.  For
59example if you have two stations XYZ and XXX, both with an instrument MKII
60which has the same transfer function for all three components then you should
61add the lines
62
63XYZ-BH-Z MKII
64XYZ-BH-N MKII
65XYZ-BH-E MKII
66XXX-BH-Z MKII
67XXX-BH-N MKII
68XXX-BH-E MKII
69
70to the external table.  Then the appropriate simulation filter for WWSSN-LP
71would be 'MKII_S+WWSSN_LP.FLF'.
