# AB Magnitudes and Fluxes

AB magnitudes (see Oke, J.B. 1974, ApJS, 27, 21) and fluxes are given for each filter

In the header of the table the keywords ABM0X, ABF0X and E2JYX are given for each filter (where X is a filter). The keywords give the AB magnitude zero-point, the conversion factor from count-rate to AB flux and the conversion factor from flux to Janskys, respectively. The first two values are obtained from the OM calibration files.
