[Castor-users] About normalization and attenuation input file format

[Kajal Aggarwal]

Hello Xiaozhuang Wang,

For normalization, you will have to provide a header (.Cdh) and a binary
(.Cdf) file containing appropriate normalization factors. I am also working
with normalization factors while reconstructing images using CASToR and to
begin with normalization, I started by reading the normalization file given
in the benchmark so as to understand the format. I am attaching a simple
code I use to read my binary normalization files.

Further, in order to include the normalization factors, in the file
castor-GATERootToCastor, while writing the event in the datafile ( LM in my
case), I include the normalization factors by providing the command
Event->SetNormalizationFactor(norm), where norm represents the
normalization factor for respective castor ID 1 and castor ID 2.

Regards,
Kajal Aggarwal
