The file x_onedspec.e.ssun2112 is a statically linked Solaris executable for the V2.11.2 ONEDSPEC package. It includes the fixes for bugs 414/409. The only incompatibility with V2.11.1 is the TELLURIC task which has a new parameter. The parameter file is below. The executable should be installed as noaobin$x_onedspec.e ($iraf/noao/bin.ssun/x_onedspec.e). ==== onedspec$telluric.par ==== # TELLURIC input,s,a,,,,List of input spectra to correct output,s,a,,,,List of output corrected spectra cal,s,a,,,,List of telluric calibration spectra ignoreaps,b,h,no,,,Ignore aperture numbers in calibration spectra? xcorr,b,h,yes,,,Cross correlate for shift? tweakrms,b,h,yes,,,Tweak to minimize RMS? interactive,b,h,yes,,,Interactive tweaking? sample,s,h,"*",,,Sample ranges threshold,r,h,0.,,,Threshold for calibration lag,i,h,10,0,,Cross correlation lag (pixels) shift,r,h,0.,,,Initial shift of calibration spectrum (pixels) scale,r,h,1.,1e-10,,Initial scale factor multiplying airmass ratio dshift,r,h,1.,0.,,Initial shift search step dscale,r,h,0.2,0.,0.99,Initial scale factor search step offset,r,h,1.,0.,,Initial offset for graphs smooth,i,h,1,1,,Smoothing box for graphs cursor,*gcur,h,"",,,Cursor input airmass,r,q,,1.,,Airmass answer,s,q,"yes","no|yes|NO|YES",,Search interactively?
