Apr 18, 2021 at 13:25 | comment | added | DavePhD | @EricTowers no, 1/(2.7 × 10^(-20)) = ~4 x 10^19 . I just worded my statement in terms of the reciprocal, and rounded to 1 digit. The paper gives 3 values in table 1 (1.8, 2.7 and 2.7 × 10^(-20)) like the preprint. | |
Apr 14, 2021 at 20:54 | comment | added | Eric Towers | @DavePhD : Their preprint only has $<2.7\times 10^{-20}$ of ${}^{16}$O/H (from Table I). Did their result shift by a factor of $20$ between 23 April 2007 (the arXiv v2) and 23 April 2007 (Phys. Rev. D)? | |
