We present new measures of the evolving scaling relations between stellarmass, luminosity and rotational velocity for a morphologically-inclusive sampleof 129 disk-like galaxies with z_AB<22.5 in the redshift range 0.2<z<1.3, basedon spectra from DEIMOS on the Keck II telescope, multi-color HST ACSphotometry, and ground-based Ks-band imaging. A unique feature of our survey isthe extended spectroscopic integration times, leading to significantimprovements in determining characteristic rotational velocities for eachgalaxy. Rotation curves are reliably traced to the radius where they begin toflatten for ~90% of our sample, and we model the HST-resolved bulge and diskcomponents in order to accurately de-project our measured velocities,accounting for seeing and dispersion. We demonstrate the merit of theseadvances by recovering an intrinsic scatter on the stellar mass Tully-Fisherrelation a factor of 2-3 less than in previous studies at intermediate redshiftand comparable to that of locally-determined relations. With our increasedprecision, we find the relation is well-established by <z>~1, with nosignificant evolution to <z>~0.3, \DeltaM_stellar ~ 0.04+/-0.07 dex. A clearertrend of evolution is seen in the B-band Tully-Fisher relation corresponding toa decline in luminosity of \DeltaM_B ~ 0.85+/-0.28 magnitudes at fixed velocityover the same redshift range, reflecting the changes in star formation overthis period. As an illustration of the opportunities possible when gas massesare available for a sample such as ours, we show how our dynamical and stellarmass data can be used to evaluate the likely contributions of baryons and darkmatter to the assembly history of spiral galaxies.
