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

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.
