The DAOPHOT aperture photometry of the M92 fields was carried out using an 8 diameter aperture and 5 wide sky annulus for each source. This is a relatively large aperture and is thus influenced by more noise in the background sky than is desirable. If the image quality is good enough, better signal-to-noise measurements can be obtained using a smaller aperture and an aperture correction term that corrects to an effectively infinite sized aperture. This correction factor is traditionally measured from the photometric curve-of-growth taken from images of relatively bright, high-signal-to-noise points stars in uncrowded regions. The use of small apertures plus correction terms also makes it possible to use aperture photometry in more crowded regions.
