Abstract:
    We present a catalogue of surface-brightness profiles (SBPs) of 125
    Galactic globular clusters, the largest such collection ever gathered.
    The SBPs are constructed from generally inhomogeneous data, but are
    based heavily on the Berkeley Globular Cluster Survey of Djorgovski &
    King. All but four of the SBPs have photometric zero points. We derive
    central surface brightnesses, King-model concentrations, core radii,
    half-light, and other fraction-of-light radii where data permit, and
    we briefly discuss their use.

Description:
    The data for individual objects are in tables file. The header
    information, which provides the Chebyshev and power-of-x coefficients,
    for each cluster are in tables.hdr file

Note on Name: hp stands for HP 1 (Cl Haute-Provence 1 in Simbad)

Note on DataSet:
  The CCD data follow a naming convention: "C" stands for data taken
  at CTIO; e.g. "CRB1" stands for the first "B" image from the CTIO
  1.5m reflector with the RCA chip. "L" stands for the Lick 1 m Nickel
  reflector: these datasets are labeled as, e.g. "LTR-B", the second
  frame from the Lick Nickel reflector, taken with the T1 chip through
  the Spinrad "R" filter. See Sec. 2.1 of printed paper for details
  of chips and filters. "DJB2" stands for the second "B" image taken
  by Djorgovski. For Terzan 5, "I" refers to an I-band image from
  CTIO kindly provided by Dr. T. Armandroff. "UPGA.4" means the first
  ("A") ultraviolet ("U") plate used for photographic photometry
  ("PG") of the cluster in question. "SCAN" data are scanning
  photoelectric photometry. "ANN" data are centered-aperture
  photoelectric photometry. Photographic star counts are referenced
  by plate number; see caption to Figure 2 in printed paper for
  references.
