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". - 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。 - - - - prefixed unit - 補助単位 - - - - - - - - - - - has unit - 単位を持つ - - - - - - - - - - - - - - - - - - has prefix - 補助単位を持つ - - - - - - - - - - - - - - unit multiple - 単位倍量 - - - - - has factor - 因子を持つ - - - - - - - - - - - - - - - - singular unit - 単数単位 - - - - - compound unit - 複合単位 - - - - - unit multiplication - 単位乗算 - - - - - has term 1 - - - - - - - - - - - - - - has term 2 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - unit exponentiation - - - - - has base - - - - - - - - - - - - - - has exponent - - - - - - - - - - - - - - - - - - - - - - - - unit division - - - - - has numerator - - - - - - - - - - - - - - has denominator - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - prefix - A prefix is a name that precedes a basic unit of measure to indicate a decimal or binary multiple or fraction of the unit.

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: m1 - m2 = @@ -35524,7076 +35524,7076 @@ where m1 - m2 is the magnitude difference between two objects, and f1 and f2 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.

absolute magnitude (M), used as a distance measurement. Distances can be expressed in distance modulii as $$m-M = 5\log d + 10 = 10-5 log \varpi$$ where \(d\) is the distance in kiloparsec and \(\varpi\) is the parallax in milliarcseconds. - - - - - m-M - - - - extinction - extinctie - Total extinction at a specific wavelength. The extinction is caused by dust and gas between a star and the observer.

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). + + number dry leaves + aantal verdroogde bladeren + + #dry leaves + Aantal verdroogde bladeren. + + + - + + number yellow leaves + aantal vergeelde bladeren + + #yellow leaves + Aantal yellow bladeren. + + + - + + number abscised leaves + aantal gevallen bladeren + + #abscised leaves + Aantal gevallen bladeren. + + + - + + number wilted leaves + aantal verwelkte bladeren + + #wilted leaves + Aantal verwelkte bladeren. + + + - - + + number rotten leaves + aantal rotte bladeren + + #rotten leaves + Aantal rotte bladeren. + + + - Strömgren magnitude - - A magnitude measured in one of Strömgren's standard passbands (using a standard filter, u, b, v, or y) or in the passbands defined by Crawford (β_narrow or β_wide). + + number nonturgid leaves + aantal slappe bladeren + + #nonturgid leaves + Aantal slappe bladeren. + + + - - - - - - - - + + cause end of vase life dry leaves + oorzaak einde vaasleven bladverdroging + + dry leaves + Oorzaak einde vaasleven bladverdroging (1/0). + + - - - - - Cousins magnitude - - A magnitude measured in one of Cousins standard passbands (using a standard filter, i.e. I or R). - - - - - - - - - Thuan and Gunn magnitude - - A magnitude measured in one of Thuan and Gunn's standard passbands (using a standard filter, i.e. g). - - - - - - - U magnitude - Johnson U magnitude.
