* [http://www.lpi.usra.edu/resources/apollo/frame/?AS12-51-7485 AS12-51-7485] is probably the most impressive orbital Hasselblad photograph of '''Catena Davy'''.<br />

==Additional Information==<br />
<br />
* IAU page: [http://planetarynames.wr.usgs.gov/Feature/1058 Catena Davy]<br />
* Several of the small craters of which this chain is composed were given informal names during the preparation of [http://www.lpi.usra.edu/resources/mapcatalog/topophoto/77D1S1/ Topophotomap 77D1S1(10)]. Since the names on those maps were adopted by the [/IAU IAU] in 1976, they have entered the [/IAU%20Nomenclature IAU Nomenclature] as [/Minor%20Feature Minor Features].<br />
* Near the middle of the crater chain (at 11.049 S/6.374 W in the coordinate system of LTO 77D1) there is a fairly prominent crater 2.6 km in diameter and about 400 m deep (according to the contours on LTO 77D1). It is labeled Davy YA on the Geologic Map. This crater has no IAU name. The ones that ''are'' named are the six craters to the immediate east of this: [/Susan Susan], [/Osman Osman], [/Priscilla Priscilla], [/Alan Alan], [/Delia Delia] and [/Harold Harold], with [/Harold Harold] -- 200 m deep -- touching the inner east wall of Davy Y (the [/lettered%20crater lettered crater] on whose floor most of the chain lies) -- and [/Susan Susan] -- just 70 m deep according to the LTO -- being virtually undetectable on Earth-based photos or on the Clementine image shown here. The fact that [/Susan Susan]..[/Harold Harold] (as opposed to the more prominent craters in the chain) received names is a completely arbitrary twist of fate having to do with the exact area that happened to be mapped in Topophotomap 77D1/S1 and the whimsy of the cartographer. They have no special significance. Why these sub-feature names were not assigned in a more logical sequence (such as alphabetically), and why these and the many of the other [/Minor%20Feature Minor Feature] names appearing on the Topophotomaps came to be recognized by the IAU (when the map-makers appear to have asked that they not be) is lost in the mists of time.<br />
* Aside from [/Susan Susan]..[/Harold Harold], the only other crater in the chain to have an official IAU name is the large one at the west end: Davy C, with a diameter of about 3.3 km and a depth of about 300 m. On the Geologic Map, the similarly sized crater at the east end is called Davy YD. It is just outside the rim of Davy Y and may or may not be part of the chain, geologically. In any event, Davy YD is no longer an official name, nor is Davy YA.<br />
* It might also be noted that Topophotomap 77D1/S1 is oddly titled "Davy Catena" and on it, the chain is labeled that way. The word "Catena" is intended as a prefix in the IAU system and the name is written "Catena Davy" on all other maps where it appears. The chain does not seem to have had a name in [/Blagg%20and%20M%C3%BCller Blagg and Müller] or the [/System%20of%20Lunar%20Craters System of Lunar Craters].<br />
* Additional trivia: LAC-77 and Geologic Map I-566 (which uses LAC-77 for its background) shows 5 equally spaced craters, link peas in a pod, between "Davy YA" and the wall of Davy Y. The chain is depicted much more accurately on LM-77, based on Lunar Orbiter and Apollo photos. There are actually 4 peas-in-a-pod craters in this interval ([/Osman Osman], [/Priscilla Priscilla], [/Alan Alan], [/Delia Delia]) with [/Harold Harold] similarly-sized, but detached to the west; and two or three non-descript craters in the space between Davy YA and [/Osman Osman] -- [/Susan Susan] is the easternmost of these. The number of small craters between Davy YA and the wall of Davy Y is not 5, but more like 7 or 8.<br />
* Based on the shadows in [http://www.lpi.usra.edu/resources/lunarorbiter/frame/?4108 LO-IV-108H] and [http://www.lpi.usra.edu/resources/lunarorbiter/frame/?4113 LO-IV-113H], the depth of Davy YA (the prominent crater in the middle of the chain) is about 520 m. Davy C (the 3 km diameter crater at the west end) is about 550 m deep. The pea-pod craters average about 300 m in depth. [/Delia Delia] is a bit deeper than that; while [/Priscilla Priscilla] and [/Harold Harold] are shallower. [/Susan Susan] and the similar unnamed crater between her and Davy YA are too shallow to cast full shadows at the sun angle of these photos. There is an additional pit about 1 km in diameter and 150 m deep touching the east rim of Davy YA. <span class="membersnap">- [http://www.wikispaces.com/user/view/JimMosher [[Image:JimMosher-lg.jpg|16px|JimMosher]]] [http://www.wikispaces.com/user/view/JimMosher JimMosher]</span><br />

==Nomenclature==<br />
<br />
* Named from nearby crater. ([/Davy Davy])<br />
* This feature was labeled '''Davy I''' in the ''[/System%20of%20Lunar%20Craters System of Lunar Craters]'' and presumably, due to the latinization of such names in 1961, was intended to be read as '''Rima Davy'''.<br />
* The name '''Catena Davy''' was provisionally introduced on [http://www.lpi.usra.edu/resources/mapcatalog/LTO/lto77d1_1/ LTO-77D1] (for which it served as the chart title). It was also provisionally called '''Davy Catena''' on [http://www.lpi.usra.edu/resources/mapcatalog/topophoto/77D1S1/ Topophotomap 77D1(S1)], in which form it served as the chart title. <span class="membersnap">- [http://www.wikispaces.com/user/view/JimMosher [[Image:JimMosher-lg.jpg|16px|JimMosher]]] [http://www.wikispaces.com/user/view/JimMosher JimMosher]</span><br />
