03/04 2008 *** Electronic efficiency corrections: The correction data for the electronic efficiency is currently provided to j_ima_iros by the subroutine 'get_EEFF_array.c'. The data in this routine have been through several iterations, the effect of applying this correction is apparntly nonlinear (?). For the moment only three parameter periods are considered for each instrument: period 1 period 2 period 3 JEM-X1 all orbits <= 44 45 <= orbit <= 166 all orbits >= 167 (reference) JEM-X2 all orbits <= 44 45 <= orbit <= 173 all orbits >= 174 The electronic efficiency corrections can be disabled in j_ima_iros by including bit 2048 in the 'develop' flag. This will leave the electronic efficiency correction active for JEM-X1 period 3 (Carls efficiency correction). To disable the electronic efficiency for all periods you must include the 1024-bit in 'develop'. ************************************************************************ 14/01 2008 *** Parameter periods for JEM-X1 revolutions startPID HV Discr.
