[IDV #VRB-317344]: Conversion of infrared data to temperature

Greetings Ben,

McV is the way to go for this case. What kind of issues were you having getting 
McV to run? I ask because many of the machines at SSEC are Macs running Snow 
Leopard, so it's odd that it won't work for you.

Cheers,

Sean
