NOTE: The bolometric correction tables were computed from the C3K grid (Conroy et al., in prep) of 1D atmosphere models (based on ATLAS12/SYNTHE; Kurucz 1970, 1993). [Fe/H] ranges from -4.00 to -3.00 in 0.50 dex steps and from -3.00 to +0.75 in 0.25 dex steps. Av ranges from 0 to 6 and Rv=3.1.

Note on photometric systems and zeropoints
Each set of bolometric corrections is specified on either the Vega or AB magnitude system. For ease of conversion amongst the AB, ST, and Vega systems we provide a table containing one line for each filter in our collection. The contents of the file can be used to convert amongst AB, ST, and Vega magnitude systems as follows.
filter system mag(Vega/ST) mag(Vega/AB)
WISE_W1 Vega 6.610497 2.665543
Above is the information for WISE W1, which is tabulated by default in Vega mags (as noted in column "system"). To convert WISE mags from Vega to AB is a simple operation:
mag(AB) = mag(Vega) + "mag(Vega/AB)" [column 4 in the file]
For example, a star with WISE_W1(Vega) = 0.0 would have WISE_W1(AB) = 2.66(...).
