[Radiance-general] evalglare question

[Michael Martinez]

Hi folks, 

I'm using evalglare on  a 180 degree fisheye image generated by Radiance. It seems that the program is identifying a glare source of unknown location and luminance in the image, and as a result gives no value for DGP or the other glare metrics. Here's the output when using -d:
