... Consequently, it is inappropriate to expand and in ordinary spherical harmonics. The proper expansion expresses both and simultaneously in terms of a particular order of generalized spherical harmonics. ... Generalized spherical harmonics start at , and for each , . ... Generalized spherical harmonics obey a sum rule analogous to a familiar one for ordinary spherical harmonics, but it includes an explicit phase factor which depends on the orientation of the two lines of sight. ...

... 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. ...
