Abstract:The FLAIR Shapley-Hydra (FLASH) redshift survey catalogue consists of 4613 galaxies brighter than b_J_= 16.7 (corrected for Galactic extinction) over a 700-deg^2^ region of sky in the general direction of the Local Group motion. The survey region is a 70x10{deg} strip spanning the sky from the Shapley Supercluster to the Hydra cluster, and contains 3141 galaxies with measured redshifts. Designed to explore the effect of the galaxy concentrations in this direction (in particular the Supergalactic plane and the Shapley Supercluster) upon the Local Group motion, the 68 per cent completeness allows us to sample the large-scale structure better than similar sparsely-sampled surveys.

The FLAIR Shapley-Hydra (FLASH) redshift survey catalogue consists of
4613 galaxies brighter than b_J_= 16.7 (corrected for Galactic
extinction) over a 700-deg^2^ region of sky in the general direction
of the Local Group motion. The survey region is a 70x10{deg} strip
spanning the sky from the Shapley Supercluster to the Hydra cluster,
and contains 3141 galaxies with measured redshifts. Designed to
explore the effect of the galaxy concentrations in this direction (in
particular the Supergalactic plane and the Shapley Supercluster) upon
the Local Group motion, the 68 per cent completeness allows us to
sample the large-scale structure better than similar sparsely-sampled
surveys. The survey region does not overlap with the areas covered by
ongoing wide-angle (Sloan or 2dF) complete redshift surveys. In this
paper, the first in a series, we describe the observation and data
reduction procedures, the analysis for the redshift errors and survey
completeness, and present the survey data.
Note that there are some minor change/improvements over the example
table published in MNRAS:
1. R.A./Dec. is now J2000 rather than B1950.
2. l/b are now given to 3 decimal places rather than 1 decimal place.
3. Some additional redshifts from NED and ZCAT have been included.
