Dr Andrew Smith

I have converted the STScI Calspec spectra from there original fit table format to a “flat” fits format that can be read by BassProject and ISIS. One or two obscure spectra did not convert. I have included some notes (with spelling mistakes) and a Excel catalogue culled from the two on the Calspec site.

I have sent a copy of the 20.5 Mb zip file to Andy to consider making it available from the BAA web site.

I eyeballed all the spectra and checked a small random sample against the originals using Tim Lester’s PlotSpectra which can display the original along side the converted ones.

Here is a comparison of the original and converted spectra of Alpha Lyr. Black is converted blue original.

I anyone needs it now I am happy to email it to you. 

Regards Andrew
