WebApr 9, 2024 · One approach to producing a VEM uses a combination of three programs: Astrometrica, Focas and kphot. In this method the magnitude of the coma is measured in six concentric photometric apertures of radii 5.6 – 33.6 arcsec. As the photometric aperture increases, the estimated magnitude will also increase since more of the coma is included.
