Supplementary Notes 

The periods, magnitudes, amplitudes and classifications for V1-27 are
from the study by Rosino (1961).   However, Rosino noted that there is a
constant zero-point error in the magnitudes that he derived.

The RA and dec are from the paper by Samus et al. (2009).

A BV colour magitude diagram by Brocato et al. (1996) shows a well
defined blue HB.  Saviane et al. (2010) showed evidence for an intrinsic
internal abundance spread among giant branch stars in NGC 5824.
