Description
VIKCAL performs radiometric corrections to planetary images acquired by
the Viking orbiter cameras. VIKCAL performs a radiometric correction in
two steps. First, VIKCAL corrects for the varying response of the
vidicon across the field of view of the camera. Multiplicative and
additive correction coefficients, as a function of line and sample
position, are applied to an image array to produce the results of an
'ideal' camera. VIKCAL converts the image data to radiance factor
values. The radiance factor is defined as the ratio of the observed
radiance and the radiance of a white screen, normal to the incident rays
of the Sun.
