Gravimetric_WC calculation looks screwy #38

Closed bpbond closed 8 years ago

Those values can't be right, dumbass. Go back and check.

Hi @apeyton could you check some numbers for me?

For example, look at core AL 10. During the experiment, its mass was generally measured at 1440-1450 g. In the Revised_Core Dry Mass.xlsx spreadsheet you sent, though, it's listed as CoreSleeve_Mass = 151.9 g, Nonsoil_Mass_>2mm = 836 g, and Soil_Dry_Weight_<2mm = 1139.71 g. These three sum to 2128 g...so we're getting a negative gravimetric water content. Other cores have the opposite problem, with insanely high WCs. See below: wc At this point (see commit 09d0924) I don't think it's a mistake in the script, so if you could double-check those Revised_Core Dry Mass.xlsx numbers that would be great. Thanks!

Note - turned out to be data sorting error. New data look much better: wc_gravimetric ...although still a couple oddities. AL 8 is very high (77% at the beginning, maybe a typo in dry mass measurement?) and AL 2 goes negative (probably a typo in the very last mass measurement).

@apeyton will check those two cores. More later!

AL 2 definitely had a data entry mistake. AL 8 seems to be correct as far as we can tell; just a very wet core. Corrected, and code added, in commit 306bd36. Closing.
