- I would like to calculate the relation between inverse steradian and arcmin^-2 for density of galaxy with a telescop.
Hello,
I am using a code on EUCLID future mission. The original author of this code has set a value for the density of galaxy equal to :
ng = 354543085.80106884
I think this is expressed in inverse steradian. I think that EUCLID mission has a 30 arcmin^-2 value for density of galaxies.
Is the conversion correct betweeen 30 arcmin^-2 and 354543085.8010688 sr^-1 ?
and how to do this conversion ?
Indeed, I would like to calculate ng with a density of 48 arcmin^-2
Regards
