Limit selection of output Jacobians for limb-viewing spectra
to tangent point perturbations only
Normal Jacobian calculations for all combinations of tangent
points and perturbations
JAC Flag must also be enabled
(and with same incompatibilites)
Also Incompatible with
ZEN Flags, since limb-viewing mode required
*JAC section perturbation altituded must
be defined using the TAN field, and therefore
limb-paths must also be specified by atmospheric tangent points,
i.e. using *TAN as the section header
rather than *GEO or *ELE.
The purpose of this option is to restrict the potentially large
number of output spectra that can be generated in limb-viewing mode
if only the Jacobians for tangent point perturbations are required.
