Abstract (from CDS):

MAIA, an acronym for Mercator Advanced Imager for Asteroseismology, is a three-channel instrument that targets fast-cadence three-colour photometry, installed at the 1.2-m Mercator telescope at the Roque de los Muchachos at La Palma (Canary Islands, Spain). This instrument observes a 9.4x14.1-arcmin2 field-of-view simultaneously in three wavelength bands on three large frame-transfer CCDs. These detectors were developed for ESA's cancelled Eddington space mission and were offered on permanent loan to the Institute of Astronomy (KULeuven, Belgium). MAIA uses its own ugr photometric system that is a crude approximation of the SDSS system. The instrument is designed to perform multi-colour observations for asteroseismology, with specific emphasis on subdwarf and white dwarf single and binary stars. We describe the design of the instrument, discuss key components, and report on its performance and first results.

within radius arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!).
