magnitudereporting
Magnitudereporting is the practice of recording and communicating quantitative measurements of an astronomical object's brightness as a magnitude. In photometry, magnitude is a logarithmic scale in which smaller numbers denote brighter sources. Magnitudereporting covers both apparent magnitudes, which reflect distance, extinction, and filter throughputs, and absolute magnitudes, which represent intrinsic brightness at a standard distance. It may also involve bolometric magnitudes that aim to summarize total emitted energy across all wavelengths.
A typical magnitude record includes the object identifier, the observed magnitude value, the measurement uncertainty, the
Standards and conventions in magnitudereporting employ several magnitude systems, notably the Vega, AB, and ST systems,
Caveats include variability of sources, filter mismatches, and changes in atmospheric or instrumental conditions. Best practices
