| DESCRIPTION |
|---|
"sdelay" carries out a fringe search of correlated data (K5's cout format).
| SYNOPSIS |
|---|
sdelay --- interactive operation
sdelay will display candidate directories that contain "cout" format files.
or
sdelay cout_file --- non-interactive operation
where cout_file is K5 software correlator output file
or
sdelay [PP] [options] --- interactive operation
where PP : to make each PP output
or
sdelay cout_file [PP] [options] --- non-interactive operation
or
sdelay [options]
or
sdelay --version --- show program version
or
sdelay HELP|?|--help --- show how to execute
or
sdelay env --- show environmental variables used in this program
| OPTIONS | |||||||
| -v | verbose | ||||||
| -cout coutfile | set correlator(cor or fx_cor) output file name | ||||||
| -sdir coutdir | set search start cout file directory to read | ||||||
| -cdir coutdir | set cout file directory to process all | ||||||
The differnce between -sdir and -cdir is as follows,
| |||||||
| -ppout | make output file of each PP data by every channel besides normal sdelay out file. | ||||||
| -nosingle | force output to multiple files (default: all results are output in a single file) | ||||||
| -odir outdir | sdelay output directory | ||||||
| -pgplot device | set PGPLOT device (/NULL for suppression) | ||||||
| -ps | set graphics out to PostScript (pgplot.ps or gnuplot.ps) | ||||||
| -2nd t2dot | search up to 2nd order rate and set search range from -t2dot to +t2dot (default for t2dot is 1.0e-13 s/s^2) | ||||||
| -fringe | plot fringe phase and amplitude | ||||||
| -pcal | plot PCAL phase and amplitude | ||||||
| -vspeplot | plot video cross spectrum and output spectrum data to "vspeout.txt" file | ||||||
| -no3d | suppress plot of coarse search function | ||||||
| -noplot | suppress all graphics plots\\ | ||||||
| -integ tinteg | force integration time to tinteg sec. (default is all available period) | ||||||
| -vanvleck | make Van Vleck correction using r=sin(r_c*pi/2) where r is true correlation coefficient, and r_c is coefficient for 1-bit samplig data. This option will be neglected in case of multi-bit AD data. | ||||||
| -out ofile | output 2D array data to a text file besides normal sdelay out | ||||||
| -classic | classic axis style (no tic marks) for 3D plots | ||||||
| -tzoom tzoom | delay axis zoom-up factor tzoom >= 1.0) | ||||||
| -tshift tshift | delay axis shift value when tzoom is set (sec) (set new center value for delay axis). | ||||||
| -bpf flow:fhigh[:fact][,flow:fhigh[:fact][,flow:fhigh[:fact][,.....]]] | |||||||
set BPF by lower and higher cut-off frequencies (upto 20 sets)
| |||||||
| -bpf2 fc:bw[:fact][,fc:[bw][:fact][,fc:[bw]:fact][,.....]]] | |||||||
set BPF parameters by center frequency and bandwidth (upto 20 sets)
| |||||||
| -fres fres | set frequency resolution (MHz) (deflt is automatic) | ||||||
| -delpcal ch#:fs[:fi][,ch#:fs[:fi][,....]]]} | |||||||
| set PCAL signal frequencies to reject by channel ch# -- channel number (starting from 1) fs -- lowest frequency of PCAL signals in baseband (MHz) fi -- interval of PCAL signals (MHz) | |||||||
| frequencies of PCAL signals removed are
fs, fs+fi, fs+2fi, fs+3fi, ... when fi is omitted, only fs is removed | |||||||
| bandwidth of rejection filter is four-times the resolution of FFT (# of FFT is double # of lags at correlation processing). this can be changed by option `-pcalbw' below | |||||||
| or | |||||||
| -delpcal delpcal_file | set file name which describes PCAL signal rejection information | ||||||
| -pcalbw bwmhz | set bandwidth of PCAL rejection filter (MHz) | ||||||
| default bandwidth is four-times the resolution of FFT (# of FFT is double # of lags at correlation processing) | |||||||
| -line[mode] | set line spectrum mode. 1st FFT size is set as same as lag size | ||||||
| -hanning | apply Hanning filter on correlation function | ||||||
| -lag[size] lag | set new lag size to reduce lag size (should be a power of 2). Note: This option cannot be used with `-hanning' and/or `-vanvleck' options | ||||||
| -sub[panels] 1|4|9|16 | |||||||
| set # of subpanels in a main panel compulsory (default is automatic) (Note: only PGPLOT support this parameter) | |||||||
| -nodel[ay_correction] | |||||||
| no delay correction in integrated video spectrum | |||||||
| -obs[out] | display observed results and total fringe phase (default is no display) | ||||||
| -so[ffset] start_offset | set start time offset (float sec) (default is 0.0) | ||||||
| -fmt8 mode | set Format 8 COUT file (cross spectrum) processing mode | ||||||
| 1: double the # of frequency component like FMT 7 (default) | |||||||
| 0: no double the # of frequency compnents | |||||||
| -w_mode mode | set frequency elements doubler mode for checking | ||||||
| 1: using FFT method | |||||||
| 2: using linear interpolation | |||||||
| 3: using vector interpolation (default) | |||||||
| -nodouble[fmt8] | same as "-fmt8 0" | ||||||
| -no_w | same as "-fmt8 0" | ||||||
| -no_rev[erse] | non-reverse frequency axis for FMT8 | ||||||
| -sdelo[ut] sdelfile | set sdelay out file name (default is "sdelayout.txt") | ||||||
| -snr2 | display SNR2 using noise level computed from a search function | ||||||
| -ch chn | set CH# to display (default: display all channels) | ||||||
| -zmax zmax | set maximum value of fringe amplitude in a search-function plot compulsory (default is auto) | ||||||
| -noin[fo] | suppress information of file name and processing date in a search-function plot | ||||||
| -notitle | -nohead | suppress header part in a search-function plot | ||||||
