The perturbation method is based on the small-parameter expansion of an unknown solution of the light scattering problem in a vicinity of the exact solution. ... The only probably exclusion is the case of anisotropic particles for which the rigid solution is either impossible or too complicated. For such problems the perturbation method can give information of the first approximation, which is important for understanding of the basic principles of influences of the material anisotropy. ...

... Since GCVS IV, there was no new GCVS edition. ... Main reasons for the automatic-survey new variables remaining outside the GCVS for a long time:  different level of detail of the classification systems, no perfect software for automatic classification available;  individual approach to each star that was always used in the GCVS cannot be applied any longer, but the experience of automatically- updated catalogs evidences for the number of errors ...
