According to the documentation, for example module SPKEZR, since recently
the light-time-corrected, apparent velocity includes a factor
(1 - d(LT)/d(t_eph)).
Can anyone provide a reference for this derivation?
It doesn't match what I get starting from relativistic addition of
although I'm sure there needs to be a dilation term like that.
Sorry if this dredges up old discussions; I wasn't able to them if so.
