Distance | R Documentation |
The purpose of this function is to generate an object that contains the projected distance to the observed galaxy in a variety of units. Supply a single input (i.e. distance in units of redshift "z", physical distance "Mpc", or angular distance "kpc_per_arcsec") and all others will be contained by the object.
Distance(z, Mpc, kpc_per_arcsec)
z |
A numeric describing the distance measured to the observed object in units of redshift, z. Precision to +/- 1e-7. |
Mpc |
A numeric describing the distance measured to the observed object in units of physical distance in mega-parsec. Precision to +/- 1e-3. |
kpc_per_arcsec |
A numeric describing the distance measured to the observed object in units of angular distance in kilo-parsec per arcsecond. Precision to +/- 1e-5. |
Returns an object of class "Distance" that summarises the projected distance to the object and the associated units.
Distance(z = 0.3)
