Abell 1367: a high fraction of late-type galaxies displaying HI
  morphological and kinematic perturbations
  To investigate the effects the cluster environment has on Late-Type Galaxies
(LTGs) we studied HI perturbation signatures for all Abell 1367 LTGs with HI
detections. We used new VLA HI observations combined with AGES single dish
blind survey data. Our study indicates that the asymmetry between the high-and
low-velocity wings of the characteristic double-horn integrated HI spectrum as
measured by the asymmetry parameter, Aflux, can be a useful diagnostic for
ongoing and/or recent HI stripping. 26% of A1367 LTGs have an Aflux ratio, more
asymmetrical than 3 times the 1{\sigma} spread in the Aflux ratio distribution
of an undisturbed sample of isolated galaxies (2%) and samples from other
denser environments (10% to 20%). Over half of the A 1367 LTGs, which are
members of groups or pairs, have an Aflux ratio larger than twice the 1
{\sigma} spread found in the isolated sample. This suggests inter-group/pair
interactions could be making a significant contribution to the LTGs displaying
such Aflux ratios. The study also demonstrates that the definition of the HI
offset from the optical centre of LTGs is resolution dependent, suggesting that
unresolved AGES HI offsets that are significantly larger than the pointing
uncertainties (> 2 {\sigma}) reflect interactions which have asymmetrically
displaced significant masses of lower density HI, while having minimal impact
on the location of the highest density HI in resolved maps. The distribution of
Aflux from a comparable sample of Virgo galaxies provides a clear indication
that the frequency of HI profile perturbations is lower than in A 1367.
