User:Rfassbind/Minor planet merge subpages test

The merger of subpages in the List of minor planets was implemented in April 2016. See post at WT:AST.

All subpages using a " " were redirect to, and their content of 100 asteroids merged into the corresponding partial list displaying 1000 asteroids. Before the merger, subpages were used up to asteroid number 200,000 (i.e there were 2,000 subpages, each with 100 asteroids). The Category:Lists of minor planets by number shows all partial lists, including the first 200 pages that had their subpages merged.


 * Changes made:
 * amended table headers
 * revised page footer
 * added id-anchor every 10 items (backward compatible w/ current #Rs)
 * added min-width styles to tables
 * using semi-automated web-tool for the upcoming merger
 * users and  will take care of the subpages after the merger (as per discussion).


 * Outlook

These changes (layout, anchors every 10 items, footer) will be implemented for pages above #200,000 (which never used subpages) as well. However, from 218 k onwards, these lists are currently not complete (i.e. they contain less than 1000 entries per page). They need to be completed, before all the above mentioned changes can be implemented (i.e. anchors). In order to do so, all MPC observatory names must be mapped to their corresponding article on wiki.

Colors
A minor planet's category (main-belt, Jupiter trojan, NEO, etc.) can be represented using a color code, which is also used for the subheadings in the infobox of the corresponding article.

Several variants are possible:
 * coloring only one cell, two cells or the entire row
 * adding a new column (MP-category) or simply adding a color to an existing column (most likely the "name"-column or "ref"-column)
 * using a simple color scheme (based on JPL-data) or a more elaborated version, adding main-belt families and NEO-group links as well (using data from LCDB, and algorithms based on orbital parameters)
 * for the simple, JPLdata based one-or-two column version, a distinction could be made between inner- and outer main-belt asteroid, using a modified color (darker/lighter yellow) as e.g.
 * (used for 13096 Tigris)
 * (not used in example)
 * (not used in example)

Coloring MBAs (i/m/o) in grey-scale, full row

 * Grey-scale colors based on either LCDB inner/middle/outer, not on Kirkwood gap definition)
 * (2.6 &lt; a &lt; 2.7);, standard
 * (a &gt; 2.7;
 * (a &lt; 2.6);  (white)
 * above classification is from LCDB's readme file, see: 2. Taxonomic/orbital class. Alternatively, a division (i/m/o) by Kirkwood gaps at 2.50 and 2.82 AU seems also reasonable (larger fraction are then labelled middle. This alternative division is more towards JPL's Small Body DB, which only labels MBAs with an inner/outer tag for much extremer cases: outer MBA 3.2 AU < a < 4.6 AU and inner MBA a < 2.0 AU; q > 1.666 AU, with a minimum perihelion to distinguish them from Mars-crossers).
 * the example list below also contains two Jupiter trojans
 * for two MBA entries, the orbital family acronym is displayed and linked in column "Ref"
 * the color used in the "infobox planet" template for MBAs (currently yellow) should be amended to grey (#D2D2D2), a distinction between inner, middle and outer MBA seems not helpful. The color-scheme needs to be amended to avoid conflict (as "satellites" are categorized in grey; the scheme, however, has not yet been implemented for satellites at all and many of them have custom colors anyway).

Grey-scale: avoid over-colorization using 3-grey-color scheme for i/m/o-MBAs, which account for more than 80% of listed entries. Full row colors are much easier to handle, are less prone to maintenance syntax errors (manually as well as automated).

<!--

Link-visibility: use ligher colors
If the first column contains a color, and especially when Jupiter trojans are displayed, replace the standard color-scheme   with lighter , to avoid problems with a link's visibility (MP-artilce link). In fact the colors could also be lightened up for NEOs, MCs, DPs and KBOs/SDOs, as long as the xxFFFF – FFxxFF – FFFFxx pattern remains the same and consistency with the infobox color-scheme remains intact,
