Description Usage Note Source References Examples

A numeric vector of velocities in km/sec of 82 galaxies from 6
well-separated conic sections of an `unfilled`

survey of the Corona
Borealis region. Multimodality in such surveys is evidence for voids
and superclusters in the far universe.

There is an 83rd measurement of 5607 km/sec in the Postman
*et al.* paper which is omitted in Roeder (1990) and from the
dataset here.

There is also a typo: this dataset has 78th observation 26690 which should be 26960.
