Description (last modified by MatthewWhiting)

We installed Duchamp 1.61 successfully and confirmed that my installation is good by running VerifyDuchamp?.sh. However, when we give our FITS file it give us the following error.

$Duchamp -p input1
WARNING <Reading parameters> : PGPlot has not been enabled, so setting flagXOutput, flagMaps, flagPlotSpectra and flagPlotIndividualSpectra to false.

Duchamp failed with the following error:
Unable to open image file allsky.fits   

We made sure our FITS file is not damaged by opening the file in a different FITS file viewer.

Is there any special formatting we should do for the FITS files before use in Duchamp?

It would be really great if you could give a hint about the possible mistake.

We also installed the cfitsio and wcslib. We think we linked them correctly, because the Verification script ran successfully.

Thanks

Thanks. The dimensions of the FITS file (as reported) seem to be strange, and judging by the 2nd WARNING message (which is garbled due to a bug, but I can see where it is coming from), there is something strange about the WCS in the FITS file.

I'm happy to take a look at it in more detail if you are able to make the FITS file available. How big is it? You can email me download details if you are able to make it available on a website or similar.

If you're not able to do that, are you able to show the FITS header here so I can see what we are working with?
