[daip] AIPS: HOWTO: Gridding- Spheroidal functions

[VMV]

Dear Mr/Mrs!

VMV> AIPS documentation and the most of the books on CLEAN mention the so
VMV> called spheroidal functions used by gridding algorithm. I was unable
VMV> to find the exact mathematical definition of that functions (which are
VMV> used specially for gridding). Can you please shed a light on what
VMV> functions are exactly used?

LK> Dorogoy Vasiya,

LK> You can find the exact mathematical definition of the spheroidal function
LK> at the AIPS COOK BOOK volume 2 in the section G.GLOSSARY, page G-17.

Thanks, but it still remains unclear how to calculate this
eigenfunction. Are there any polinomial representations of this
function or something?

                                      Thanks,
                                      Vassili M Vitrichtchak,
                                             MSU
