There are many catalogues of photometric standard stars. A catalogue of primary standards for a given photometric system is usually published when the system is defined. For widely used systems further catalogues of `secondary' standards will often be compiled by making observations calibrated with the original primary standards. Recent catalogues of standards are usually available in a computer-readable form.
Some suitable catalogues of secondary standards are: Johnson and Morgan[44], Landolt[50,51,52,53], Christian et al.[9], Graham[30] and Menzies et al.[57,58]. Landolt's catalogues are, perhaps, the most useful.
