R_DEL dimension comments - R_DEL is a function of R_DIST, which itself is a function of bin size and theta, but having defined R_DIST, it should now be the basis on which R_DEL is calculated. So for example (assuming Matlab indexing), for a central difference scheme evaluated at bin 10 i.e. R_DIST(10), the two-bin separation R_DEL(2) = R_DIST(11) - R_DIST(9), whereas for a forward difference scheme evaluated at bin 10, R_DEL(2) would be R_DIST(12) - R_DIST(10). The R_DEL(2) values will be identical, but the principle is that R_DEL is the separation distance distance the velocity observations being compared. | |||
