incorrect info in the right table relative to its cited source

Latest comment: 6 months ago1 comment1 person in discussion

According to the cited source https://ntrs.nasa.gov/api/citations/19700026405/downloads/19700026405.pdf for the wiki table on the right, there is "Table I.- A P O L L O SPACECRAFT ENGINE SPECIFICATIONS - Concluded" on page 9 in the row named "LEM Ascent" (aka APS/LMAE) have the data that is not aligned with the table :

- first error for wiki table's variable Burn time listed as ~~200 seconds~~, but the source says "Total burn time, sec" for LEM is 465 seconds.

- second error is in its Dimensions:

Length 510 Inches (1,300 cm) - it appears that the OP probably wanted to print 51 Inch (1,30 cm/1.3 m) just as the source says it is as

"Overall length", so less by a factor of 10.

Diameter ~~100 inches (250 cm)~~ - not sure where OP found this number and what "Diameter" of an engine even mean (the largest cross

section diameter of any part/chamber ?), but there first googled search showed me the link to https://airandspace.si.edu/collection-objects/rocket-engine-liquid-fuel-apollo-lunar-module-ascent-engine/nasm_A19721168000 where dimensions are in cm and feets.... (i hate US customary units), so probably better to extrapolate the data for Length and Width/diameter from there and cite it as a source, since it's a air and space museum after all (somewhat credible).
