Compound plot procedures

These procedures use more elementary functions to produce diagnostic plots.


Plot the residual FDL delay in microns. If keyword slide is 1, then open a sliding plot widget.
Plot a power spectrum (or structure function if sf=1) of the delay. The time stamps must be integer multiples of the instrumental coherent integration time (2 ms currently at NPOI). Example: plot_delayseries, fdlstamp(),fdldelay('AE0-AW0').
Plot visibility power spectra in a special browser plot.
Plot mean of squared visibility amplitude averaged over numav samples (default 10 samples) as a function of k frequency.
Display image of fringes from the frame data.
Display fringe frames in a special browser window. Example: plot_images,bincounts
plot_powerpeaks,baseline$<$_int$>$[,beam$<$_int$>$,scanfile$<$_char$>$] [,numav=numav]
Compute and plot scatter plots of primary and secondary peak heights in the fringe powerspectra.
plot_spectrumpeaks,baseline$<$_int$>$[,beam$<$_int$>$,scanfile$<$_char$>$] [,channels=channels][,numav=numav]
Compute fringe spectra of the squared visibility amplitude averaged incoherently over numav samples as a function of fringe frequency. Make a scatter plot of the peak amplitude at the k value corresponding to the selected baseline, versus the maximum peak amplitude over all the other fringe frequencies which are not supposed to contain any signal.
plot_groupdelay,baseline$<$_int$>$[,beam$<$_int$>$,scanfile$<$_char$>$] [,numav=numav][,classic=classic][,slide=slide]
Plot the groupdelay.
For the specified baseline, plot the corrected fringe phase. If beam is not specified, use currently loaded data. With the datum parameter, all available scan files will be read and analysed.
plot_dispsol,baseline$<$_int$>$[,beam$<$_int$>$,scanfile$<$_char$>$] [,compute=compute][,classic=classic]
Plot the dispersion corrected delays, along with the raw FDL delays for comparison.
Plot count rate histograms for the specified channels.
Plot coherence analysis for the selected baseline and channel.
Plot NAT count rate histograms.
