For non-spherical isotropic particles, the classic variant of the RDG approximation does not include the anisotropy of the shape and hence does not give the correct Rayleigh limit, say, for small ellipsoids. ... We call this variant a modified RDG approximation (MRDG). ... First, the MRDG leads to the correct Rayleigh limit. ... The second approach to generalization of the RDG is connected with the use of the Born iterations for the scattering integral equation [ 95 , 124 , 132 , 264 ]. ...

... This chapter describes the PEPSYS package for general photometric reductions. The function of photometric reductions is to measure and remove, so far as possible, the instrumental signature from the data. ... The package contains two main parts: a planning program and a reduction program. The planning program interacts with the user to find out the goals of the observing program, and then produces a schedule of the observations needed to meet those goals efficiently. ...
