: The two Doppler shifts are the "same".  If v << c,
: the relativistic formula reduces to the non-relativistic one.

: Your posting seems to imply that these are two different
: expressions that need to be used depending on relative velocity.

: They aren't.  The relativistic one reduces to the non-relativistic
: one in the the limit that v << c.

What ARE you smoking, Anderson? What IS the limit of v << c?
Negative infinity, perhaps?
