These procedures use more elementary functions to produce diagnostic plots.
plot_fdldelay,baseline_int
[,beam
_int
][,/slide]
Plot the residual FDL delay in microns. If keyword slide is 1, then open a sliding plot widget.plot_fdlpower,baseline
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_vispower,baseline
Plot visibility power spectra in a special browser plot.plot_fringepower[,channels=channels][,numav=numav]
Plot mean of squared visibility amplitude averaged over numav samples (default 10 samples) as a function of k frequency.plot_fringeimage[,channels=channels]
Display image of fringes from the frame data.
plot_images,frames
Display fringe frames in a special browser window. Example: plot_images,bincountsplot_powerpeaks,baseline
Compute and plot scatter plots of primary and secondary peak heights in the fringe powerspectra.plot_spectrumpeaks,baseline
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
Plot the groupdelay.plot_fringephase,baseline
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
Plot the dispersion corrected delays, along with the raw FDL delays for comparison.plot_ratehist,channels
Plot count rate histograms for the specified channels.plot_coherence,baseline,channels
Plot coherence analysis for the selected baseline and channel.plot_nathist,sid
Plot NAT count rate histograms.
