Rachel simulated yield output

''This page stub will be updated when a new version of Rachel is released.''

The output to the terminal following a "simulated yields" calculation will be similar to the following until the next release version where the formatting will be improved.

Three columns have ambiguous names:

* The "Measured Counts" column gives the true particle-gamma count emitted into the solid angles of the particle and Ge detectors.  This is equivalent to the total counts for the beam run if the detectors were blackbodies (had 100% efficiency), or if the raw counts were corrected for the absolute p-gamma efficiency. 
* The "Raw Counts" column is only used in this output and is not passed to Gosia.  The raw counts are the estimated p-gamma counts in the raw data, assuming an approximate absolute efficiency for Gammasphere.  
* The "Sim. eps" column gives the assumed absolute efficiency <math>(\epsilon_{abs})</math> of the Ge detector used to calculate the value in the "Raw counts" column.  

Note that the "Measured Counts" are not sent to Gosia as they appear in the table.  

Before the measured counts are sent to Gosia they are divided by the solid angle of each Ge detector to match Gosia's calculation of yield per unit solid angle.  (This is true in Rachel versions >= 2.0.7.beta; in earlier versions this solid angle factor was neglected.)  All yields sent to Gosia are then multiplied by <math>4\pi</math> so that weak transitions have counts >=1.  This overall multiplicative constant of <math>4\pi</math> has no effect on fitting.
