              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;
