Micrometre

I don't think I've met an astronomer who uses "micrometers" rather than microns. Jleous 02:57, 7 November 2005 (UTC)

Neither have I. Normal wikipedia style, I guess, would be for micrometers, but the use of mircons in this context is so widespread that it should be change back - prehaps with a wiki-link to Micrometer." --Jason Kirk 10:53, 7 November 2005 (UTC)

I made the change to the article and only later noticed it was being discussed here. It may not be so common, particularly in some regions such as the USA. But the micrometre is understood by astronomers and used by them. It is interesting to note what the IAU says:

• The name micrometre should be used instead of micron. IAU
• IRAS fully met its objective to make a complete survey of the infra-red sky in the 8,120 micrometre wavelength.OOSA
• The 15-micrometre mapping of the western section of W 50 reveals more probable sites of interaction between jets and that nebula, but what is the nature of the emission observed? Service d'Astrophysique du CEA
• From this, an IRAS color-color region for PPNs was identified, which was later extended to include all IRAS 25 micrometer peakers.Valparaiso University Indiana, Department of Physics and Astronomy
• Parallax measurements could not be taken around midnight, so Olivier began a micrometer measurement of double stars program. Department of Astronomy, University of Virginia
• Two images of Cassiopeia A obtained at 24 micrometer with the Spitzer Space Telescope over a one year time interval show moving structures outside the shell of the supernova remnant to a distance of more than 20 arcmin. Department of Astronomy, University of Arizona
• IRCAM operated in the 1-5 micrometre region of the electromagnetic spectrum. UK Astronomy Technology Centre
• In the case of Jupiter, whose temperature is -145°C, heat radiation would not seem to be of great importance because the planet is so cold. Its radiation is faint and peaks up at an infrared wavelength of about 40 micrometres. Journal and Proceedings of The Royal Society of New South Wales

I realize that this is a discussion that was held a long time ago, but I would like to say that all astronomers use the term "micron" and not "micrometer". For example, check http://www.jach.hawaii.edu/JCMT/continuum/intro.html and http://ssc.spitzer.caltech.edu/geninfo/. These are two websites for major telescopes in infrared and submillimeter astronomy, and they use micron. The references given by Bobblewik are exceptions.George J. Bendo 16:39, 5 August 2006 (UTC)
