-==Quickly representing a summed 4pi array==
-Gosia can quickly integrate the p-<math>\gamma</math> events over a <math>4\pi</math> Ge array without adding a detector at every laboratory position.  In order to do this, the output file 9 can be modified to make the first two attenuation coefficients 0 for all orders.  (File 9 is the output of OP,GDET, commonly called the *.gdt file.  For Gammasphere the *.gdt file would look something like
-<pre>
-.0
-.000E-02
-.  0.  0.9951
-.  0.  0.9854
-.  0.  0.9711
-.  0.  0.9521
-.  0.  0.9379

-.  0.  0.8699
-.  0.  0.8349

-where the first two columns have been set to 0. to simulate a 4pi array.  In this case the <math>\epsilon_\gamma</math> value would
-still be the absolute photopeak efficiency, but <math>\Delta\Omega_\gamma</math> would be 4*pi.
-See the manual entries on OP,GDET and "Gamma Detector Solid Angle Attenuation Factors" for more information on these attenuation coefficients.
