I'm getting this error from psrzap:
% psrzap -v GUPPI_J2339-0533_56798_42824_0001.fits
>> Using baseline method
DynamicSpectrumPlot data min/max = (0.00187616574112326,0.0604446046054363)
%PGPLOT, PGIMAG: not enough colors available
This happens on my Mac, running OS X 10.9.3 and XQuartz 2.7.6. My PGPLOT_DEV is set to /xs.
My guess is that one window eats up 256 colors and the other then can't allocate colors. I'm not sure how to work around this. Can I tell psrzap to use the TrueColor visual or something like that?
