angsize(dl,z,h0=,k=,lambda0=,Omega_m=,q0=,silent=)
Compute the apparent angular size of an object as a function of
redshift.
INPUTS: dl - proper size of the object (in kpc)
z - redhsift values
EXAMPLE: plot the angular size of a 50 kpc diameter galaxy as
a function of redshift for the default cosmology
(Lambda = 0.7, Omega_m=0.3) up to z = 5
z = span(0.1,5,100) //Angular size undefined at z = 0
pg,angsize(50,z),z;
xytitles,"z","Angular Size (\")"
