Hi
Just wondering if anyone could help me here.
Im having a problem with dispcor.
Im going into epar dispcor.
Im getting an error:

ERROR: DISPCOR : Echelle dispersion function not found (database/eclampspec)

in the parameter for defining where the dispersion data is to be found I have the correct place to look.

Thanks,

There are two types of dispersion functions in the IRAF spectral software. One is for echelles and one is for single order. The distinction is whether they are produced by ecidentify/ecreidentify or identify/reidentify. The message you report is what you get when you have an extracted echelle spectrum that you are trying to dispersion correct and there is no echelle solution corresponding to the REFSPEC keyword(s).

So make sure you've done everything consistently with the echelle tools and not the single order tools.

The solutions are usually created in a database subdirectory (automatically created for you) of the directory having the spectra being calibrated. It is possible to do things differently but the path noted in your message seems reasonable. Maybe you changed directories? So see if you can find the file eclampspec somewhere.
