Hi Luca and All,

I have a few comments:

Why would it say it is using run #0?

Can you print out the EcalChannel you are passing to getChannelConstants before this error?
(Looks like there are EcalChannel.getChannelId/Slot/Crate/X/Y methods.)

Do you need to divide by the gain to get the ADC?  I thought that raw energy was directly available?
Alternatively, you could just multiply your new scale factors by the cosmic gains in the end.
