Website Ann: Table of 2,373 near crater depths from the Apollo era

http://members.csolutions.net/fisher...ApolloEra.html

This is to announce a website regarding lunar crater depths for approx
2,300 smaller nearside craters made during the Apollo era.

Approximately 1,896 higher-precision nearside crater depths from the
Apollo era by Pike (1976) and Arthur (1974) and 477 low-precision
crater depths by Cherrington (1969) were digitized and are presented
here for amateur lunar enthusiasts' use. Pike (1976) and Arthur (1974)
report a kilometer precision to two significant digits for crater
diameters and crater depths. The standard source of the USGS Gazetteer
of Planetary Nomenclature reports only crater diameters in whole
kilometers. The Gazetteer does not report crater depths. Another
standard reference source for crater depths and diameters is the
Appendix in Westfall's Atlas of the Lunar Terminator (2000). Westfall's
Appendix table concerns about 830 named-craters but reports no depths
or diameters for smaller satellite feature craters. In the table
presented here, 1,637 (69%) smaller satellite depths and diameters are
digitized; 684 (29%) larger named-crater and other feature measurements
from Cherrington (1969), Arthur and Pike are digitized.

Appendix in Westfall (2000) remains the best source for named crater
depths. The Cherrington chart take-offs from the 1960s have a very low
accuracy. This digitized table provides higher-precision supplemental
measurements for smaller satellite craters measured during the Apollo
era.

The table, by feature name, can be directly linked from:

Arthur (1974) is a portion (N=1,900) of the 7,000 plus nearside crater
catalogue
prepared by Chuck Wood in the 1970s, discussed in this LPOD:

This website was substantially revised inorder to expand and narrow its
focus on Apollo era higher-precision crater depth measurements.
Discussion was expanded to include more detail on the Clementine era
digital elevation model accuracy and more recent advances in measuring
the height and depth of lunar topography using Earth-based radar
interferometry down to an uncertainty of 20 meters. Recent advances in
amateur Earth-based height and depth measurements of lunar features to
a 100 meter accuracy level are reviewed.

In addition to preexisting digitized list of 1,933 smaller crater
depths from the Apollo era (by Arthur, Wood and Andersson), the site
now includes digitized versions of Westfall's _Atlas of the Lunar
Terminator_ Feature Appendix on larger named craters and the
Kapral-Garfinkle GLRG 2005 dome catalogue. This limited non-commercial
internet distribute was graciously authorized by both respective
authors.

Plotting files for these compiled catalogues are provided for use with

A master compiled list of catalogue data on crater depth and feature
depth-heights (N=3,444) is at:

http://members.csolutions.net/fisher...atsByName.html

The master list is sorted such that where there is more than one
measurement in a source catalogue, the assumed highest precision
measurement appears first in the list.
