Actual (unknown) values

Parallax, distance	ϖ	D = 1 /ϖ
		equatorial	Galactic
Peculiar velocity	v	v _α , v _δ , v _r	v _l , v _b , v _r
Peculiar proper	μ_v = v/D	μ_{α ∗ ,v} = v_α/D	μ_{l ∗ ,v} = v_l/D
motion		μ_δ,v = v_δ/D	μ_b,v = v_b/D

Proper motion:	μ_{α ∗} = μ_{α ∗ ,G} + μ_{α ∗ ,v}; μ_δ = μ_δ,G + μ_δ,v

Measured (nominal) values

Parallax, distance	ϖ ′	D′ = 1 /ϖ′

Velocity^a	v ′
Proper motion^a	μ ′

Notes.

^(a)

The measured values differ from the actual values not only due to measurement error, but also due to correction for Galactic rotation.
