Issue with kinematic fitting failing #33

Closed siangphillips closed 9 months ago

siangphillips commented 9 months ago

Hi,

I'm trying to use 3DBbarolo to fit simulated high-redshift galaxy data cubes. I have been able to successfully do this with one datacube, but with another the fitting errors out with this message:

Preparing a bunch of cool outputs... Extracting guileless 2D maps... Done. Deriving sublime radial profile... Done. Calculating the very last model...corrupted size vs. prev_size Aborted (core dumped)

I have tried to investigate this error but I don't recognise it and couldn't find any useful information on how to deal with it. Do you have any idea what could have caused this error? I was running 3DBbarolo with a .par file, where the .par file has this structure:

FITSFILE Opuntia_bbarolo.fits OUTFOLDER Opuntia 3DFIT true NRADII 2 RADSEP 0.16 VSYS 161.673 XPOS 6.5 YPOS 6.5 INC 60.0 Z0 0.001 FREE VROT VDISP TWOSTAGE True NORM AZIM MASK SEARCH SNRCUT 3 GROWTHCUT 2.8 NORMALCUBE True

Many thanks, Sian

Hello Sian, thanks for using BB for your research!

That is an error that I've never seen before, so I'll need to investigate it further. It may be due to some parameter in the fits header that the code is not understanding.

Can you please send me by email the datacube and the parameter file that gives the error?

Thanks, Enrico
