	Durchmusterung - Wikipedia, the free encyclopedia
		Durchmusterung is a German word for a systematic survey of objects or data.
		The decadal work of the Bonner Durchmusterung (abbreviated by BD) tabulates the positions and apparent magnitudes of approximately 300,000 stars to apparent magnitude 9–10.
		The Cordoba Durchmusterung (abbreviated CD) was made visually — similar to the former BD), but the Cape Photographic Durchmusterung (CPD) was conducted by the new photographic technique, which just before was shown to have sufficient accuracy.

	Star catalogue - Wikipedia, the free encyclopedia
		The Bonner Durchmusterung (german: Bonn sampling) and follow-ups were the most complete of the pre-photographic star catalogues.
		The Bonner Durchmusterung itself was published by Friedrich Wilhelm Argelander, Adalbert Krüger, and Eduard Schönfeld between 1852 and 1859.
		It was further supplemented by the Cordoba Durchmusterung (580,000 stars), which began to be compiled at Córdoba, Argentina in 1892 under the initiative of John M. Thome and covers declinations -22 to -90.

		All of the fainter stars shown on the Durchmusterung charts were not put on the diagrams, but it is believed enough of them are given to permit a ready identification of objects in any part of a photograph.
		The magnitude in the third column is the visual estimate for the star as given in the Bonner or the Cordoba Durchmusterung.
		The right ascensions and declinations as given are, in general, not the Durchmusterung positions but have been taken from the catalogues of the Astronomische Gesellschaft and have been rounded off to the tenth of a second of time in a and the tenth of a minute of arc in d.

	Star catalogue
		The Bonner Durchmusterung and followups were the most complete of the pre-photographic star catalogues.
		As it covered only the northern sky and some of the south, this was then supplemented by the Southern Durchmusterung (1886, 120,000 stars), which was then supplemented by the Cordoba Durchmusterung (580,000 stars), which ran through the south in 1892.
		Star names from these catalogues include the initials of which of the four catalogues they are from (though the Southern follows the example of the Bonner and uses BD), followed by the angle of declination of the star, followed by an arbitrary number as there are always thousands of stars at each angle.

	Cordoba Durchmusterung (Site not responding. Last check: 2007-11-01)
		The "Cordoba Durchmusterung" (CD, Thome 1892-1932) is a visual survey of southern stars in the declination zones -22 to -89 deg, carried out as an extension to the "Bonner Durchmusterung" (BD) catalogs of Argelander (1859-1862) (see also Kuestner 1903) and Schoenfeld (1886).
		The data in the machine-readable "Cordoba Durchmusterung" were keypunched directly from the published catalog at the National Space Science Data Center (NSSDC).

		The survey was performed using techniques similar to those used for the BD, i.e., the stars were cataloged by allowing the telescope to drift along the mean declination of each zone and recording the positions and magnitudes of stars crossing the transit line of the field.

		A final duel purpose forcefield type is the stealth 6-hit, which is similar to the standard 6-hit, but is designed to limit the output radiation that may lead to detection.
		The individual catalogues are the Bonner Durchmusterung (BD), the Sudentliche Durchmusterung (SD), the Cordoba Durchmusterung (CD), and the Cape Photographic Durchmusterung (CP).
		Originally the names of stars listed in the Durchmusterungs consisted of a pair of letters identifying the individual catalogue, followed by a plus or minus and the declination (as viewed from a telescope on Earth).

		Due to the expansion of the dust shell it is expected that the circumstellar dust extinction becomes smaller, leading to an increase in the brightness at short wavelengths.
		In the Cordoba Durchmusterung (Thome 1914) a visual magnitude of 9.4 has been estimated for AFGL 4106.
		The size of this overlap region is mainly based on the estimated errors of the Cape Observatory Photographic Durchmusterung and the Cordoba Durchmusterung.

	CD-46 11540 / Gl 674
		Its designation as CD-46 11540 came from a visual survey of southern stars begun in 1892 at the Astronomical Observatory of Cordoba in Argentina under the direction of its second director John M. Thome (1843-1908).
		Thome died before the completion of this southern sky atlas in 1914, when 578,802 stars from declination -22° to -90° were published as the Cordoba Durchmusterung ("Survey").
		The BD and CD were greatly expanded and extended into the modern age of photographic surveys with the subsequent creation of the Cape Photographic Durchmusterung from South Africa.

	Cape Photographic Durchmusterung
		The CPD (CPD, Gill and Kapteyn 1895-1900) is a photographic survey of southern stars in the declination range -18 deg to -90 degrees.
		The original goal of the work was to carry out a southern survey similar to those of the "Bonner Durchmusterung" (BD, Argelander 1859-1862) and the Cordoba Durchmusterung (CD, Thome 1892-1932) but using photographic plates to provide a permanent record of the sky at the epoch of observation.
		The probable error of a photographic magnitude, as determined by combining results for different magnitudes and weighting proportionately according to the numbers of stars in each class of magnitude, is given as +/- 0.055 mag.

	Star Names
		Faint stars need catalogue names too and the most famed general catalogue for fainter stars, the "Bonner Durchmusterung" (the Bonn Survey), was compiled in Germany in the nineteenth century and lists stars to tenth magnitude.
		BD and CD are sometimes combined as "DM" for "Durchmusterung." Precession has now moved many stars out of their original declination strips.
		The most commonly used catalogue for all stars is the Henry Draper (HD) Memorial Catalogue, which serially numbers stars through roughly tenth magnitude to the east of the vernal equinox (according to right ascension in the year 1900) independent of declination.

		Nowadays (epoch 2000) Polaris has the declination 89°16' and the rectascension 2h31.5m, but at the time of Argelander (epoch 1800) Polaris was to find at 88°15' declination and 0h52.5m rectascension, and therefore Polaris is sorted under the declination of 88 degrees.
		Under the direction of J.M. Thome (1843-1908) from 1892 on the southern sky was mapped at the observatory of Cordoba (Argentina).
		Together with the Bonner Durchmusterung it built a systematical catalog of more than one million stars up to tenth magnitude, made before the age of the photographic surveys.

		The following modifications to the original format were made in order to make the data easier to process by the general user while still retaining all information and coding in the original data set: 1.
		All records were condensed by eliminating unused bytes between the data fields in order to make room for the addition of Durchmusterung (DM) numbers for the HD stars.
		DM numbers were inserted into the records by retrieving them from an updated and corrected version of the SAO-HD-DM-GC Cross Index (Warren and Roman 1981) which had been sorted by HD number.

	HD 44594 / HR 2290
		The star can be found: northwest of Canopus (Alpha Carinae); northeast of Beta Pictoris; west of Tau Puppis; southwest of Nu Puppis; and south of Eta Columbae.
		The star was first designated as CD-48 2259 in a visual survey of southern stars begun in 1892 at the Astronomical Observatory of Cordoba in Argentina under the direction of its second director John M. Thome (1843-1908).
		As a relatively bright star in Earth's night sky, HD 44594 is also catalogued as Harvard Revised (HR) 2290, a numbering system derived from the 1908 Revised Harvard Photometry catalogue of stars visible to many Humans with the naked eye.
