Nevertheless, based on Hall measurement, it is clear that the H-doped a-IGZO HECL layer has a much higher bulk carrier mobility (at 14.6 cm2/Vs) than that in as-deposited a-IGZO (below detection limit at approximately 0.01 cm2/Vs).

However, analyses at both Rocknest and the Yellowknife Bay study site by the Chemistry and Mineralogy (CheMin) instrument of MSL found only calcium sulfates, suggesting that if iron sulfate is present it exists at levels below detection limits at these locations (Bish et al., 2013; Vaniman et al., 2014).

In addition, two different approaches were applied to recover part of the potential information carried out by the protein analytes that showed a significant percentage of samples with values below detection limit in at least one of the groups (depressed, schizophrenics and controls), with the percentage of "censored values" differing between the groups.
