Query: The 2MASS Tully-Fisher Relation and Local Peculiar Velocities   This study assesses the utility of applying the Tully-Fisher (TF) relation
using photometric data from the 2MASS project. This is achieved by performing a
preliminary analysis using 2MASS extended source data with the SCI sample of
Giovanelli et al. (1997). Distances and peculiar velocities are measured for 11
clusters out to approx. 75/h Mpc. Statistics are found to be limited by the 47%
coverage of the current 2MASS second incremental release. However, the 2MASS J,
H and K-band photometry produce results in good agreement with those derived
from the SCI I-band data. These results are also generally in reasonable
agreement with Giovanelli et al.s' (1997, 1998) own analysis. Comparison of the
results obtained with two different 2MASS magnitudes suggests they are not
overly sensitive to the type of magnitude used. It is concluded that the 2MASS
TF is a useful tool for distance and peculiar velocity work, especially with
the improved coverage that will be provided by the full 2MASS release.
  A general discussion of the Tully-Fisher relation and previous work,
particularly in the near-infra-red, is also presented.
