Hi,

Did anyone use the LIRIS data reduction package?

I haven't used the package myself and see that it hasn't been asked about before, but if you could post a more specific question about a problem you're having perhaps we can help.

Hi Admin,

Thanks for your response.

According to the LIRIS data reduction package example, I have to use lcpixmap, lspskynod an lspnodcomb. When I do lspnodcomb, I receive the following error message

hr_h_flats_MasterFlat.fits is not an image or a number
hr_h_flats_MasterFlat.fits is not an image or a number
dbdir ./database

ERROR: spectral transform file not found ./database/fchr_h_arc_long_MasterArc.fits

I am unable to understand the problem here, the files are in the same directory and still it doesnt find them and then the other errors.

Assuming you own the files and have permissions to write to the current directory, try doing

cl\$this->_split2($m[0]) reset use_new_imt = no

This will bypass the new image template code (e.g. use of the @file syntax) which may be causing a problem.

Otherwise, do all the images have a ".fits" extension or something else (or none at all)?
