2014ApJ...792..129N The Calibration of the WISE W1 and W2 Tully-Fisher Relation Neill, J. D.; Seibert, Mark; Tully, R. Brent; Courtois, Helene; Sorce, Jenny G.; Jarrett, T. H.; Scowcroft, Victoria; Masci, Frank J. Abstract. In order to explore local large-scale structures and velocity fields, accurate galaxy distance measures are needed. We now extend the well-tested recipe for calibrating the correlation between galaxy rotation rates and luminosities---capable of providing such distance measures---to the all-sky, space-based imaging data from the Wide-field Infrared Survey Explorer (WISE) W1 (3.4 micron) and W2 (4.6 micron) filters. We find a correlation of line width to absolute magnitude (known as the Tully-Fisher relation, TFR) of {M}^{b,i,k,a}_{W1}_ = -20.35 - 9.56 (log W^i_{mx}_ - 2.5) (0.54 mag rms) and {M}^{b,i,k,a}_{W2}_ = -19.76 - 9.74 (log W^i_{mx}_ - 2.5) (0.56 mag rms) from 310 galaxies in 13 clusters. We update the I-band TFR using a sample 9% larger than in Tully & Courtois. We derive {M}^{b,i,k}_I = -21.34 - 8.95 (log W^i_{mx}_ - 2.5) (0.46 mag rms). The WISE TFRs show evidence of curvature. Quadratic fits give {M}^{b,i,k,a}_{W1}_ = -20.48 - 8.36 (log W^i_{mx}_ - 2.5) + 3.60 (log W^i_{mx}_ - 2.5)^2 (0.52 mag rms) and {M}^{b,i,k,a}_{W2}_ = -19.91 - 8.40 (log W^i_{mx}_ - 2.5) + 4.32 (log W^i_{mx}_ - 2.5)^2 (0.55 mag rms). We apply an I-band -WISE color correction to lower the scatter and derive {M}_{C_{W1}_} = -20.22 - 9.12 (log W^i_{mx}_ - 2.5) and {M}_{C_{W2}_} = -19.63 - 9.11 (log W^i_{mx}_ - 2.5) (both 0.46 mag rms). Using our three independent TFRs (W1 curved, W2 curved, and I band), we calibrate the UNION2 Type Ia supernova sample distance scale and derive H_0_ = 74.4 +/- 1.4(stat) +/- 2.4(sys) km s^-1^ Mpc^-1^ with 4% total error.
