py21cmsense.conversions

Common 21 cm conversions.

Provides conversions between observing co-ordinates and cosmological co-ordinates.

Functions

X2Y(z[, cosmo, Om0, Tcmb0, Neff, m_nu, Ob0, ...])	Obtain the conversion factor between observing co-ordinates and cosmological volume.
dL_df(z[, cosmo, Om0, Tcmb0, Neff, m_nu, ...])	Get the factor to convert bandwidth to line-of-sight distance in Mpc/h.
dL_dth(z[, cosmo, Om0, Tcmb0, Neff, m_nu, ...])	Return the factor to convert radians to transverse distance at redshift z.
dk_deta(z[, cosmo, Om0, Tcmb0, Neff, m_nu, ...])	Get gactor converting inverse frequency to inverse distance.
dk_du(z[, cosmo, Om0, Tcmb0, Neff, m_nu, ...])	Get factor converting bl length in wavelengths to h/Mpc.
f2z(fq)	Convert frequency to redshift for 21 cm line.
z2f(z)	Convert redshift to z=0 frequency for 21 cm line.
