branch: master
commit e39330abbf9798996c35880fb4100a8ae95f7eca

    Zeropoint: adding sanity check for aperture option
    
    Until now, we did not have a sanity check for --aperarcsec option. Without
    this, the user did not understand that the existence of it is necessary.
    
    With this commit, a sanity check is added to zero point script. So if the
    user doesn't use this option, one error will be printed.
