We report on analysis of 308.3 hrs of high speed photometry targeting thepulsating DA white dwarf EC14012-1446. The data were acquired with the WholeEarth Telescope (WET) during the 2008 international observing run XCOV26. TheFourier transform of the light curve contains 19 independent frequencies andnumerous combination frequencies. The dominant peaks are 1633.907, 1887.404,and 2504.897 microHz. Our analysis of the combination amplitudes reveals thatthe parent frequencies are consistent with modes of spherical degree l=1. Thecombination amplitudes also provide m identifications for the largest amplitudeparent frequencies. Our seismology analysis, which includes 2004--2007 archivaldata, confirms these identifications, provides constraints on additionalfrequencies, and finds an average period spacing of 41 s. Building on thisfoundation, we present nonlinear fits to high signal-to-noise light curves fromthe SOAR 4.1m, McDonald 2.1m, and KPNO 2m telescopes. The fits indicate atime-averaged convective response timescale of 99.4 +/- 17 s, a temperatureexponent 85 +/- 6.2 and an inclination angle of 32.9 +/- 3.2 degrees. Wepresent our current empirical map of the convective response timescale acrossthe DA instability strip.
