21. High speed photometry of the system shows multiple periods of variation in the luminosity. 22. And finally, the lighting objects are associated with a photometry via IES files. 23. The subject of photometry remained in its infancy until Pierre Bouguer and Johann Heinrich Lambert. 24. In addition to astrometric data, the MPC collects light curve photometry of minor planets. 25. In 1968 a new field observatory was started at Kavalur for stellar spectroscopy and photometry . 26. The observing time is mostly assigned for the photometry of asteroids and comets and astrometry. 27. Flame photometry is crude but cheap compared to spectrophotometer ( which uses a monochromator ). 28. The 3225 Hoag asteroid discovered by photometry . 29. For example, the estimated using photometry . 30. The photometry of a light fixture describes the way it distributes its light into space.
