# Schlafly+(2016) reddening vector, based on 
# APOGEE, PS1, 2MASS and WISE.
# 
# R_V is computed using R_V = 3.3 + 9.1x, where x 
# controls the strength of the 2nd principal component 
# of the reddening vector. 
# 
# The reddening vector is normalized by setting:
#   1. A_H/A_K = 1.55 
#   2. E(g-r) = 0.901 mag for unit reddening
#
