Hi,
I have successfully installed galprop-v57 and generated different fits files and the outputs are as shown in the image attached.

someone please explain in detail about viewing these Healpix fits files and gather important information from them, by also including the steps to view them, because even though Healpix is already installed through galtoolslib, I am not able to use it for my problem (even though it might be mentioned somewhere, it would be helpful if someone explained it once again). Would appreciate a response at the earliest.
Thank you,
Harshith
