USAGE:
splist [options]
file label1 [{label2|---]
PURPOSE:
Reads BIN-sp
files written with OUTSP (ufiosps.f)
and optionally
converts admittance and phase by Hilbert means.
Label1
usually addresses the complex co-spectrum.
Label2
is optional; usually it addresses the confidence.
`---´ is an
alternative to an empty label.
A file may contain a
series of spectra, and their types (real or
complex) and lengths
may appear in any order. Let's call them
Segments.
Use
splist
file x x
to get an inventory of
a file with multiple spectra.
Segments will normally
carry a short comment, 2*8 characters long.
The comment depends on
how the main program's make use of it; it may
just be a dull reminder of the job's
id (e.g. the ins-file) or it may
posit a string to identify specifics
(e.g. in a series of
parametrized spectra).
The comment can be targeted for input
(see option -n).
For causality
analysis, use the file that sasm06
saves under
option qsavesp=.true. ( -> unit 51)
and request CSP
PSX .
For admittance
and co-phase use the files assigned by
iun_zadmit and
iun_zphase. Request CAD ADC .
Many more
processing options could be imagined.
OPTIONS:
-DBG[#v] - Debug with
msglevel v
-w <name> - Ascii output to
this file. Default is STDOUT.
-n<target> - Input the segment
marked with target in the comment part.
Must match
the comment at position 1 and through the length of target.
-n~<target> - Liberal match:
anywhere in the comment.
-n~<trg1>/<trg2>
- Not really liberal in trg1 - must be exact - ,but trg2
may
be given
with less characters. The `/´ is removed.
A ->tag<>comment<- like
->FSP<>48,2.500><7.80e-2 <- can be matched
with
splist -n~48,2.500/7.80
<file> FSP
-n/<target> - Liberal
match: anywhere in the second part of the comment.
Only one
of these sub-options can be specified. No wildcards as of yet.
-I - in
retrieval of a segment, print the file information.
For output:
-q
-
quiet, print only data
-s[#w] -
smooth ringing in gain and phase spectra weighing neighbours
with w
(default=0.5).
-scia -
auto-scale on input with the value at zero-frequency.
-sci[/]#x
- scale on input with x or, with `/´, 1/x
(acts on both file sections;
might need differentiation).
-F<fmt> - the
format part for spectral columns.
-FR<fmt> - the
format part for frequency.
-C -
Include the confidence in the output, beware context
-a -
compute admittance (or absolute value)
-alg - ... show as 10log
-aL -adB - ... in
neper or decibel
-E
- ... for psxy -Ey option.
-C
- with -aL or -adB , recalc confidence logarithmic
-EC - produce
value+error bar series based
on statistics info in file header.
-EPW - in the case
of power spectra, the statistics info
in the file header will probably contain zero
(i.e. unset) confidence limits; however, confidence
level and degrees-of-freedom are usually available.
Then, use this option to calculate the limits.
-p.. - like -a..
, assume input in power units, however
-EH - like -C
but for coherence: use confidence information
(sasm06: tag1::tag2 = KOH::KOC )
to produce value+error bar series.
-vi[#lvl] - drop insignificant values
in print (cfd < lvl, default 1e-10)
-ri[#lvl] - replace
confidence values cfd > lvl with zero
(default 1e-10)
The lvl
parameter in -iv and -ir is identical.
-cfl[#lvl] - limit confidence
value to lvl in print (default 1e16)
-Pdopt -Propt
- compute phase in degrees resp. radians.
Additional options:
j - conjugate (invert the values)
b - issue break symbols for GMT at phase jumps >
half circle
/#v - cut circle at 2π×v (at the
end of the option string!)
[default=0.5]
-W
- weed out insignificant values
-B#v
- floor for amplitudes in logarithms, default = 1.d-10
-f[0][l][n] - 0:
skip the zero-frq
n: skip the Nyquist frq.
l: print 10log(frq)
-mHz -Hz -cpd -cph
- first column gives frequency; select scale (default is
number).
For some spectral processing:
-PHS -
compute phase from gain using Hilbert tr.,
2-column output, 2nd is standard phase.
-S#t
- simulate a shift of time with t seconds (?).
-dfu#h -dff#h
- for power
spectra (tag(1:)='PS', options -a.. or -p..:
-dfu:
"un-filter" = restore spectrum for the effect of a
1-term difference filter (1,h), -1 < h
< 0
-dff:
apply the filter
-[anti]causal[-sp]
-
compute (anti-)causal part of filter (-spectrum),
(-antica and antica-sp will suffice)
-[anti]causal-spf
- compute (anti-)causal spectral factor.
(antica-sp will suffice)
-WF[m,]n <filename>
- output a Wiener filter for lags m ≤ i
≤ n
Default m = -n
-cep - compute
clog(zsp)
-cepi - compute
cepstrum, i.e. FFT-1{clog(zsp)}
-cepi:#b,#e
- use only bins b to e for cepstrum
Find out labels:
splist file X X
EXAMPLES:
(1) After sasm03 with
qsavesp=.true. in namelist, read the file that
sasm03
writes on unit 51. Assume here: sasm03.sp
Read
power spectrum in dB:
splist -Hz -pdB sasm03.sp PSX
Generate confidence information, for use in psxy -Ey:
splist -Hz -pdB -E sasm03.sp MEC PCF
(2) A lot of use is made in
~/Seismo/gcf/SCG/cal-seis
(3) After sasm06, first an
admittance spectrum's estimates, and then the series
for
plotting error bars:
cd ~/Seismo/gcf
