The spectroscopic model of the source gives
,
the number of photons received per cm
and per second at the earth,
from sky position
and at energy
(differential per solid angle and energy).
The number of photons,
, detected (per second)
in pixel
and in
PI energy bin
centered at
is obtained by multiplying
by the effective area and applying the response matrix:
