WebThe Magnitude Scale The process of measuring the apparent brightness of stars is called photometry (from the Greek photo meaning “light” and – metry meaning “to measure”). As we saw Observing the Sky: The Birth of Astronomy, astronomical photometry began with … WebIn order to obtain cleaner fittings, some filtering criteria were added to produce each colour-colour diagram. The data filtering to produce the photometric relationships can be checked in Table 5.5 and Table 5.6.The polynomial coefficients obtained with the resulting sources are included in Table 5.7 and Table 5.8.The validity of these fittings is, of course, only …
