Description:
This is a collection of line indices in the Lick system (and others)
for a collection of Galactic, M31, M33 and other globular clusters
plus bright and dwarf galaxies observed primarily at the MMT over the
period 1980-1992 by J. Huchra, J. Brodie, N. Caldwell, R. Schommer, C.
Christian and G. Bothun. The paper describing this catalog of indices
is published in Huchra, Harris & Schommer (1996, in prep).
Table 1 lists the definition of the indices used, Table 2 lists the
line indices and errors, Table 3 lists multiple measurements for
individual objects (plus dispersions and means) to give the reader a
sense of the precision and accuracy of individual measures, and Table
4 lists index measurements from higher dispersion spectra. Each of the
index tables generally has two lines, the first are the index values
and the second are the statistical (calculated from photon counts)
errors. An estimate of the external error in each index can be gotten
from the multiple measurements given in Table 3. "AV" in Table 2
indicates that the measurement given is the average of multiple
individual spectra give in Table 3. Otherwise the "RFN" number refers
to the serial number of the MMT spectrum.

Note (1): 1: Andromeda Globular Cluster. Nomenclature for the Andromeda
clusters follows Huchra et al., (1982ApJ...259L..57H), with the
Battistini et al., (1980A&AS...42..357B), number first followed
by the Sargent et al., (1977AJ.....82..947S), number.
2: M81 Globular Clusters
3: Fornax Dwarf Galaxy Globular Clusters
4: M33 Globular Cluster Candidates
5: M87 Globular Clusters
6: Virgo Dwarf Galaxies
7: Fornax Cluster Dwarf Galaxies
8: Other Dwarf Galaxies
9: Bright Galaxies. Several of the M31 cluster candidates have been
classified as foreground stars (see Huchra et al.,
(1991ApJ...370..495H) for a discussion and complete
identifications).
Theses stars can be found in the "Other Stars" (13) section.
10: Peculiar Galaxies
11: Comparison Stars
12: Cluster System Averages. N188 AV is the weighted average of the
individual NGC 188 stars.
