Segmentation Fault error at prepare PSFs step

blaisekuo opened this issue 4 years ago · comments

Hi Julian, I ran EchelleSimiulator on a spectrograph model I generated and I got a Segmentation Fault at the "Prepare PSFs" step. Any clues as to why? The HDF model file looks like it has some PSFs stored in it. I attached the model creation script I used.
model_creation_iranti.txt

Running my EchelleSimulator build on the MaroonX example seems to be working.

Ok, I've gotten past the error now by leaving just one config in the zemax file.

OK. I was just gonna write to you to send me the produced HDF file, maybe I can spot an error. Let me know if you need anything else.

Here's an HDF file I created. I am able to create the file and I can see that there are PSFs in the hdf file but when running it through EchelleSimulator I get a blank frame. I also ran the model_creation script on the zemax file provided and it also gives a blank frame.

I ran this on the command line:

./echellesimulator --spectrograph Iranti --constant 0.0001 -o ../simulations/flat.fit

Iranti.zip

Looking in the hdf file, it looks like my problem is happening in the affine transformation calculation. Most of those values are missing in the order table.
