...correction An acknowledgement of an inaccuracy and its replacement with what is believed to be the accurate information. Some publications have a regular column or space for corrections and clarifications, whereas websites tend to amend the copy itself and add a note at the end to highlight the fact that a change has been made since original publication (failure to do so, or ‘invisible correcting’, is generally frowned upon as unethical for all but the most trivial corrections). See also accuracy ; apology ; readers’ editor...

For example, if experience tells me a clock is usually 5 minutes slow I will add 5 minutes to the time it displays when I look at it, or government estimates of the number of homeless people will be higher than the recorded totals in the census, because it is known that the census will not be able to accurately record all the homeless...

... A correction is a textual alteration made to rectify a mechanical error, such as an unintentionally omitted word or a misspelling, in the writing or copying of a document. The term implies that the alteration simply amends a mistake and entails no textual rethinking by the author or scribe, nor any substantive change, such as verbal deletion or rephrasing, made to the text as originally intended. Compare emendation and revision...

...correction ( terrain correction ) A correction applied to observed geophysical values to remove the effects of topography. In gravity studies, it is the correction applied to each individual determination of gravity to allow for the attraction of rocks occurring as hills above the height of the recording station and as valleys below this level. For seismic corrections see elevation correction ; static correction...

A correction made during a space probe's flight in order to maintain its proper trajectory or speed is known as a mid-course correction . The corrections required are generally small, since trajectories are carefully calculated to conserve...

...correction ( statics ) A correction applied to geophysical data, especially seismic data, to compensate for the effect of irregular topography, differences in the elevation of shots and geophones relative to a datum, low-velocity surface layers (weathering correction), and the horizontal geometry of shots and receivers (geophones or hydrophones ), or any correction which applies to the geometry of the source and receiver(s). A static correction provides some form of direct-current shift (e.g. in seismic- reflection surveys), usually a time...

...correction The difference between the visual and bolometric magnitudes of an object. Two zero-points are in use, which differ by 0.07 mag. One defines the Sun to have zero bolometric correction. The other has its zero-point set so that bolometric corrections for all stars are positive; this is because other stars emit more energy than the Sun at non-visual wavelengths, either in the ultraviolet for hotter stars or the infrared for cooler stars. Confusingly, some authorities define bolometric correction as bolometric magnitude minus visual...

It is a combination of the free-air and Bouguer corrections. 2.
