User:Rfassbind/Mapping IAU codes

This is a working version, created to replace the current List of observatory codes. The data source for this list comes from MPCs diacritical and non-diacritical observatory codes webpages.
 * Live version List of observatory codes
 * Test version User:Rfassbind/List of ObsCodes

Design and features

 * Only one single large table or several tables grouped into sections each with 100 observatories? Using a table-sort feature for columns is more useful when only one single list exists. On the other hand, a split-up into ~20 tables is more structures and in most cases easier to maintain.
 * columns / data fields:
 * 1) Code > IAU code
 * 2) Observatory Article or Redirect named (page name) on wikipedia
 * 3) Location
 * 4) country: using flagicon or, due to list size, only the ISO--3166-alpha 3 code (3-letter code) in textual format$
 * 5) "city", from trailering part of MPC-keyword, or manually added, linked to corresponding wikipedia article
 * 6) MPC keyword (only part before any colon)
 * 7) link label  + comment + info, label used for piped links (shorter version) - "link-label" may be dropped →"comments/info" only
 * 8) article class (Redirect, STUB, START, C, B) using icon

TODOs and problems

 * Observatory vs others
 * Codes are not only given to "observatories" but also to "Surveys" and projects. The generic term "institution" as used for discoverers (institutional discoverers, category, or "Discovering dedicated institutions" a table in discoverers of minor planets list.


 * Owner vs. Location:
 * The country flag should display the location of the observatory (institution)
 * Examples
 * Canada-France Ecliptic Plane Survey is located in the USA, but a FRA/CAN project (as given in
 * ESO's La Silla would show a 🇨🇱 country flag


 * Article revision
 * Article names: Some article names seem not to conform with WP-guide lines or may need to be revised. The renaming of existing articles should be done before list is compiled (and before large edits such as LOMP revision (i.e. column "Site") is revised. Using #Rs in the base of a pipped link should be avoided in most cases.
 * Examples:
 * Campo Imperatore Near-Earth Object Survey (dashed, capitalized article), however used un-dashed #R: Campo Imperatore Near Earth Object Survey
 * Rating, template and Talk-page: the articles "class"-rating should be revised before a list is compiled. This includes:
 * addition/removal of stub-templates on articles footer
 * addition/removal of WikiProject templates on talk page, and assessment of "class" and "importance" parameters. Also, any missing parameters (listas) or a template wrapper (Wikiproject banner shell) may need to be added.

Coordinates
Conversion to geocentric latitude from the parallax constants given by the MPC:
 * 1) arctan of the quotient of MPC parallax constants (rho sin phi divided by rho cos phi), Src
 * 2) convert radiant to degree (multiply by 180°/&pi;)
 * 3) add empirical offset of 0.1916° (move calculated latitude somewhat to north, approx. 19.5 km)

Essay

 * see also d:User:Romaine/Mapping/List of observatory codes

Finding an observatory on wikipedia based on the discovery citations (at MPC, JPL etc.) can be very difficult. The List of observatory codes would be the ideal place not only to list the codes but to map the observatory names as given by the MPC with wikipedias existing articles. In addition, observatories with no article/section on wikipedia could be redirected to this list.

Unfortunately, MPC is very inconsistent. While records for a particular observation uses the code plus the observatories name, the discovery citation is much more relaxed and can be completely misleading. For code 688 the full name is "Lowell Observatory, Anderson Mesa Station", while in citations its simply "Anderson Mesa Station". Worse, discoveries made by observatory 704 are cited as, for example "Discovered at Socorro on 2008-01-31 by LINEAR", just giving the location "Socorro" instead of "Lincoln Laboratory ETS, New Mexico". Here, "Socorro" is not even part of the discovering observatory's name (as indicated by its code), while "Socorro" itself appears as part of the observatory names for H01 (Magdalena Ridge Observatory, Socorro) and 702 (Joint Obs. for cometary research, Socorro)


 * Example – current format
 * 000: Greenwich, England, UK (Royal Observatory, Greenwich)
 * 095: Crimea-Nauchnij, Ukraine (Crimean Astrophysical Observatory-Nauchnij)
 * 704: Lincoln Laboratory ETS (Lincoln Laboratory's Experimental Test Site), Socorro, New Mexico, US (also see LINEAR)
 * 716: Palmer Divide Observatory, Colorado Springs, Colorado, US

Category redundancy
The discovery category was reassigned on 15 September 2016, for a total of 119 MP-object articles/redirects. This section is linked to in each edit-comment.

There were 3 redundant DISCOVERY-BY categories:
 * Category:Discoveries by Indiana University (119 items)
 * Category:Discoveries by the Goethe Link Observatory (85 items)
 * Category:Discoveries by the Indiana Asteroid Program (120 items)

Which all should contain 119 discovered minor planets, and 3 articles (Indiana University Bloomington, Indiana Asteroid Program, Goethe Link Observatory

The new category:
 * Category:Discoveries by Indiana University (Indiana Asteroid Program)

replaces the redundant ones, which are now category-redirects. The new category contains 122 items.

On wikipedia we need to stick to the official discovery credits. It does not matter what JPL's data-feed from the DISCOVERY.DB gives as a result. The Minor Planet Center (MPC) credits all 119 asteroids, discovered during 1949-1966, to Indiana University, not to the Goethe Link Observatory or to the Indiana Asteroid Program (which would have been a better choice). The MPC credits these bodies as follows:  | discoverer     = Indiana University (Indiana Asteroid Program) | discovery_site = Goethe Link Obs.
 * "Discovered at Brooklyn on date by Indiana University..", where Brooklyn is the location of the Goethe Link Observatory (discovery site).
 * For more context, see this article
 * For minor-planet-object articles, the following parameters in Infobox planet were also amended:
