31. A Cassegrain was available for photometry , and the Chrysler Schmidt telescope was still available. 32. Regular UBV photometry of variable stars continued until 1998 when a CCD camera was first used. 33. In 2005, the Stardome contributed 250 hours of time-series photometry to this collaboration. 34. The photometry for Gamma Corvi B suggests a stellar classification in the range K5 M5 V. 35. Photometry is useful, for example, to quantify Illumination ( lighting ) intended for human use.36. The 1.3 m ( 51-inch ) large-field transit photometry of exoplanets. 37. After two sabbaticals to Harvard, Baker's interest moved from photometry to the Milky Way. 38. He developed new procedures based on colorimetry and flame-photometry which speeded up the rock analyses. 39. Primary work consists of planetary, deep sky, NEO studies, astrometry, photometry and astrophotography. 40. It is situated at photometric, with a larger number available for spectroscopic work and direct imaging photometry .
