Binary Table

Hi there,

Just trying to find the best way to turn a 12 column binary table into a plottable iraf form.

The data is an extracted single spectral order from an echelle spectrograph. The columns are various parameters such as wave, flux, col, row, s/n etc.

I can read the table into iraf with strfits and that produces a .hhh and .tab file.

What do I do with the .hhh and .tab files?

Thanks a bunch for the help

Depends what you mean by "plottable iraf form" : Once you have the table you can use tasks like TPRINT/TDUMP to write out e.g. wavelength and flux columns as text. A simple graphics tasks like GRAPH or IGI could then plot these directly. If what you want is to treat this as a real spectrum, use the RSPECTEXT task to read the columns back in as a spectrum image and you can do things like SPLOT.

Hope this helps,

Thanks Mike,
I will try that and I will post my results for others to see.
Cheers,
