Johnson magnitude
longcomment: For accurate photometry the magnitude needs to be determined over well-defined spectral regions as the spectrum of to objects may be quite different. These magnitudes are measured using filters that allows only radiation within specific spectral regions (passbands) to pass through to the detector. These filters have accurately defined transmission curves characterised by a central wavelength and a bandwidth. The UBV system devised by Harold Johnson and William Morgan has been the most important general system until recently. The precise definition requires a reflecting telescope with aluminised mirrors fitted with an RCA 1P21 photomultiplier. The U region corresponds to a region in the violet and ultraviolet, the B region corresponds to typical photographic response and the V region to the visual response region (approximating the eye's response curve).

magnitude
commonly has unit: magnitude
commonly has unit: micromagnitude
commonly has unit: millimagnitude
commonly has unit: one
longcomment: The magnitude scale was originally created by Hipparchos of Nicea (160-127 BCE) and was measured by comparing the brightness between stars. Initially this was done inaccurately by eye but is currently done by using photoelectric photometers or even more recently by CCDs. Hipparchos divided the stars into six magnitude (brightness classes), the brightest stars being assigned to the first class and the faintest to the sixth class. By about the middle 1800s it became apparent that the traditional magnitude scale is close to a logarithmic scale with base 2.5. This is due to the fact that the response of the eye is nearly logarithmic. N.R. Pogson formalised the magnitude scale to closely match the traditional (visual) scale. It is now defined as: m 1 - m 2 = -2.5 log f 1 f 2 where m 1 - m 2 is the magnitude difference between two objects, and f 1 and f 2 are the luminous fluxes of the two objects. The magnitude of Vega (α Lyrae, HD 172167) is defined to be 0 in all wavelengths and passbands, although in practice this can only be an approximation. The zero point is now defined using multiple standard stars from the north polar sequence (non-variable stars within 2 degrees of the north celestial pole) or secondary standard stars from other parts of the sky. Please note that the scale is inverted, objects of magnitude 1 have a higher luminous flux than objects of magnitude 5. Stars of magnitude 6 are just visible to the naked eye under good observing conditions. The units of magnitude, also called magnitude, are usually not indicated except when indicating small magnitude differences when milli- or micromagnitudes are used.

comment: A quantity is a representation of a quantifiable (standardised) aspect (such as length, mass, and time) of a phenomenon (e.g., a star, a molecule, or a food product). Quantities are classified according to similarity in their (implicit) metrological aspect, e.g. the length of my table and the length of my chair are both classified as length.
comment: 量とは，ある現象（例: 星・分子・食品）の定量化できる（標準化された）性質（例: 長さ・質量・時間）の表現である。量は（暗黙の）計量的類似性に従って分離される。例: 机の長さ及び椅子の長さは双方とも長さに分類される。 @ja

type: Class
comment: A unit of measure is a definite magnitude of a quantity, defined and adopted by convention or by law. It is used as a standard for measurement of the same quantity, where any other value of the quantity can be expressed as a simple multiple of the unit. For example, length is a quantity; the metre is a unit of length that represents a definite predetermined length. When we say 10 metre (or 10 m), we actually mean 10 times the definite predetermined length called "metre".
comment: 測定単位とは，量の確定的な大きさであり，慣例又は法律によって定義し採用されている。同じ量の測定の標準として用いられ，他の如何なる量の値も当該単位の単純な倍数として表わせる。例えば，長さも量である; メートルは長さの単位であり，確定的な所定の長さを表している。10メートル（又は10 m）とは，「メートル」と呼ばれる確定的な所定の長さの10倍を，実際に意味している。 @ja
