Subject: Determination of neutron capture yield and related corrections 

Here are all the files needed for calculation of the yield. There is some information that still needs to be added to the energyandyield.c file, for example the atomic mass of your target in amu, the neutron separation energy for the compound nucleus in MeV (this is needed due to using the Weighting technique). Also, you need to add some lines  to read the tof histogram, which will then be converted in a neutron energy hisogram and then divided by the flux.

For the conversion to neutron energy we assume an approximate flight path for now. We will determine this more accurately once we have the yields and fit resonances. Emma will need to use a different flux than Annie, because we have a different spallation target. Emma's flux is preliminary, so we also should look at the SILI detectors at some point.

There are some more instances where names for rootfiles and ascii files need to be added. In the first instance, please try and add the missing information and try running the code. I haven't tested it so there may be still problem.  To run it you will need to download the 3 rootfiles into the same folder (or move somewhere else and adjust the path name in the .c file.

PLEASE set variable THRESHSCALER to 1 for now. We dont know yet what it is :-)
