... Program Information . ... By design, the greater part of the observations have been done at one of two ORIENT angles in both of the two observing epochs, but by necessity, in order to accommodate the observations within the same general time frame and to also allow other GO observations to schedule, a smaller number of observations were done at a second ORIENT angle since that allowed for scheduling over a larger number of days within the larger UDF period. ... 9978 . ... 9979 . ... 9980 . ... 9981 ...

It is a matter of common knowledge that in processes of genesis and evolution of many solar phenomena participate magnetic fields of sunspots. ... As a basis for formation of the database we take data on magnetic fields, collected by set of observatories during many years of observations. ... Section "Magnetic field data" contains data of magnetic field observation for separate sunspots, presented in standard text format (ASCII). ... Description of structure of these files is presented here . ...

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 ]. ...

... 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
