Duchamp crashes

[andrew.walsh@…]

Hey Matty, just downloaded version 1.5 of Duchamap, as the old version crashed on me with a new file I am processing. Unfortunately, this version crashes as well. I suspect it might be because the fits file is 14GB, but am not sure. Here is a log of what I did:

Done. Data array has dimensions: 2880x2880x460 Opened successfully.
