dynscarg
produce a dynamical scargle periodogram of a timeseries and display PSD OBSOLETE, DO NOT USE!!!!!!!!!!!!!
time series analysis
dynscarg,tt,rr,file,ghost=ghost,dt=dt,tlen=tlen, pmin=pmin,pmax=pmax,numf=numf
tt: time rr: count rate file: file name of encapsulated PS-File to be produced
dt: time distance between individual PSDs (default: 4) tlen: length of the individual time series that are used to generate the PSD pmin: minimum period to consider (0) pmax: maximum period to consider (tlen/2) numf: number of frequency points (500) sig : significance levels (99, and 99.9 %) raterr: error bars for rate. Plot symbols instead of lines.
ghost: invoke ghostscript after plot is done grey: grey scale plot instead of color color: It's color instead of count rate tbin: Do psym=10 plots, with errors, in a way that will make even Joern happy (i.e., gaps are explicit) nolabel: Don't put a label on the ASM significance levels! chatty: be chappy
an encapsulated postscript file is produced
it is not checked whether the desired period range is meaningful
pieces of length tlen of the time series are transformed with the lomb scargle periodogram and normalized to the maximum value. The result is plotted.
Version 0.5: 1999/08/07: Joern Wilms ([email protected]) Version 0.6: 1999/08/25: Joern Wilms I hope the normalization is now finally all right... Version 0.7: 1999/08/26: Michael Nowak Added raterr as an optional input, color as a keyword, tbin as a keyword Version 0.8: 1999/08/27: JW, added sublabel keyword
