[Clas12_photon] database

[Raffaella De Vita]

Hi Kevin,
the instructions I have been using to browse the database are the ones 
at https://clasweb.jlab.org/wiki/index.php/CLAS12_Constants_Database . 
After connecting to CCDB with:
     clas12-ccdb -i
I was able to list the table/directories with the command
     ls
enter in one of the directories (i.e. calibration) with
     cd
and finally show table information with the command
     info tablename
or
     cat tablename
to display the values.
FT-Cal tables are under calibration/forward_tagger/calorimeter .
Description of these tables is available at 
https://clasweb.jlab.org/wiki/images/b/bb/FT_Cal_Calibration_Constants_V2.pdf
Cheers,
     Raffaella
