The RMS vs magnitude diagram achieved by aperture photometry after
correction of systematic errors. The data shown include around 7800 stars
at 311 epochs from a single night of WASP0 observations and only includes
those stars for which a measurement was obtained at 90% of epochs. The night
in question was 8th August, 2000 during which 50 second exposures were taken
and, although the night was clear, was during bright time. The location of
HD 209458 on the diagram is indicated by a 5-pointed star. The black curve
indicates the theoretical noise limit with the 1-sigma errors being shown by
the dashed lines either side.
