See section 5.10. The det.gdt file can be compared with the example ing1demo.tar.Output to the terminal should look like this:OPENED g1demo.outIO-num = 22 UNKNOWN FORMATTEDOPENED g1demo.inpIO-num = 25 UNKNOWN FORMATTEDOPENED det.gdtIO-num = 9 UNKNOWN FORMATTED(etc.)Additional output at this step, as well as the following steps, will be found in the g1demo.out file (unit 22).The parameters given to OP,GDET should not be changed while running this demo, because changesto the gamma-ray detector setup will introduce inconsistencies with the simulated data in g1demo.yld.2. Calculate the correction factors for the point approximations (section 5.4).Remove the OP,GDET sequence inserted in step 1. (Keep one blank line after END,.) No otherchanges are needed. Issue the same command to run Gosia a second time. (Note that this is runningthe full integration with OP,CORR inserted after OP,INTG. NTAP is set to 3, which tells Gosia toread the gamma-ray yields from file 3, in this case “g1demo.yld”.)gosia < g1demo.inpThis step may take several minutes as GOSIA calculates the Coulomb excitation and gamma-ray yieldsintegrated over the energy and scattering angle ranges specified in OP,INTG. When it is complete, thefile g1demo.cor is created (unit #4). If the file g1demo.yld (unit #3) is not found, there will be a fatalerror. See section 5.4.166
