Добро пожаловать, Гость . ... Телескопостроение, оптика (Модераторы: I.A.R. , Ivan7enych ) ? Один вопрос по ZEMAX . ... Гость . ... Записан . ... Проблема в чем: Plynomial задается как z=sum a_i E_i(x,y), а мне надо чтобы степени были для координаты по оптической оси, при использовании поворотов тоже проблема, так как и x, и y входят только с квадратом. А в zemax все поверхности (если не ошибаюсь) задаются как z=f(x,y), но никак не с квадратом ( в смысле z^2=g((x,y) ). ...

A STUDY OF THE FRAGMENT DISPERSAL AND TRAJECTORY OF THE SAYH AL UHAYMIR 001 METEORITE SHOWER. ... We obtained hundreds of GPS find locations, analyzed the fragment distribution, and developed a model of the meteorite's trajectory. ... More than 2670 samples weighing more than 450 kg have been collected. ... Increasing fragment mass along track indicated a flight direction of 233o. The fragments' mass distribution was used to model the meteorite trajectory. ...
