where: d and f - the diameter of the aperture and focal
distance of the objective;
the transmission coefficient of the
atmosphere ;
the transmission coefficient of the
optical system (illuminator + light
filter + objective)
coefficient of fall of the image
luminance over frame field;
dissipation in radiation chamber related
to the surface of the Earth;
coefficient of zonal brightness of the
object ;
coefficient of zonal brightness of terrain
mean-weighted over area within the field
of view of the optical system;
coefficients of haziness and light
dissipation in the given zone;
effective exposures during surveying and
exposure of sensitograms;
corrections for deviation from the recipro
city law and for difference in the spectral
composition of the measurements effective
during surveying and during exposure of the
sensitograms (at = ieff A± = 1 ;
at exposure of sensitogram behind the
surveying light filter A, ^ 1).
