... Columns can be re-named, added, or deleted; various operations can be performed on column contents, and the results stored in a new column; and so on. ... When you create a table from an ASCII file, the width of the table column is (by default) the width of the field in the original *.dat file. ... You can avoid this problem by specifying a width wider than the original ASCII field by using (say) C*32 instead of just C for the column in the format file, when you create the table. ...

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 ]. ...
