[Castor-users] Attenuation correction using .hdr format?

[tmerlin]

Dear Ashok,

It looks like there is an issue with your interfile header. I attached 
an example of an interfile header working with CASToR. You could also 
see the required key in chapter 8 of the documentation.

Let me know if you still encounter issues.

Best regards,
Thibaut
