      <h:acknowledgement>Appreciation is expressed to A. R. Klemola for providing the magnetic tape of the catalog and for reviewing the modifications made to the data. Dr. Klemola also kindly reviewed a draft copy of this document before its completion and printing. The work of W. M. (Bill) Owen, Jr., in correcting and updating the earlier version of the catalog, is gratefully acknowledged, as are his comments on the statistical accuracy of the positions and the revised documentation. This document was written by Wayne H. Warren Jr. and was translated from a Script version to the current standard ASCII form.</h:acknowledgement>

        <p:note><![CDATA[A magnetic tape containing the catalog, in binary format, was received from Dr. A. R. Klemola in November 1981. The data were converted to character-coded form and written to a direct access storage device for editing. The following modifications were made to the data in order to effect a more uniform format and to standardize the data representation: Plus signs were added to all positive declination zones. Missing data were converted from zeros to blanks. Since there are valid zero proper-motion data in the catalog, the source reference had to be scanned visually to locate all these values so that they could be converted back to zeros again. In the original machine-readable file, there was no way to tell between zero proper motions and missing values. All AGK3 numbers were converted to the representation +/-XX XXXX (SAO numbers were not modified). The catalog was sorted by increasing right ascension (the stars were originally in some kind of plate or measurements order).]]></p:note>

        <p:note><![CDATA[A copy of the catalog, originally archived and documented at the ADC in 1982, was sent to W. M. Owen, Jr. of the NASA Jet Propulsion Laboratory, in January 1990. Mr. Owen, having collaborated with Dr. Klemola in the preparation of the Lick Reference catalogs for the Uranus and Neptune encounters, reviewed the catalog and made the following modifications to the file: AGK3 designations and proper motions were added for 17 stars not previously identified as AGK3 stars. SAO numbers and proper motions were added for eight stars not previously identified as SAO stars. Four stars appeared in the catalog twice. Their positions and magnitudes were averaged and the duplicate entries deleted. Stars 575/8718 and 219/8718 were incorrectly identified as SAO stars; their identification and proper-motion fields were blanked out. Three AGK3 and six SAO designations were erroneous and were corrected. (The proper motions were found to be correct for these entries, however.)]]></p:note>

        <p:para><![CDATA[
    The Lick Saturn-Voyager Reference Star Catalogue was prepared for
    purposes of determining up-to-date, reasonably accurate, equatorial
    coordinates for reference stars in a band of sky against which cameras
    of the Voyager spacecraft were aligned for observations in the region
    of Saturn during the flyby. The requirements were a surface density of
    about three reference stars per observation frame of 24 sq.arcmin of
    the cameras - somewhat greater that the SAO (Smithsonian Astrophsyical
    Observatory Staff 1966) and the AGK3 (Dieckvoss et al. 1975) densities
    - and a positional accuracy +/- 0.5". Visual magnitudes were also
    required. The completed catalog contains 4551 stars in the right
    ascension range 12h 40min to 14h 12min, declination zones +02deg. to
    -09deg. Mean errors of the positions, as derived from least squares
    solutions against the Perth 70 Catalogue (Hoeg and von der Heide
    1976), are about 0.25"; however, individual residuals for some bright
    and excessively faint stars are as high as 0.5" to 1.0". The
    accidental error of one measurement, as deduced from a tabular
    histogram given in the original catalog publication (referenced
    below), is about 0.09".]]></p:para>
        <p:para><![CDATA[    Apparent photographic and visual magnitudes were derived from iris
    photometer measurements, visual magnitude being approximated from a
    derived color-index relation using UBV stars selected from the USNO
    photoelectric catalog (Blanco et al. 1968) and extended with Perth 70
    stars. The resulting magnitudes appear to have mean errors of at least
    0.2mag - 0.3mag for the brighter stars (visual magnitude < 10mag) and
    uncertainties can be as much as 0.5mag for the fainter stars. The
    magnitudes are considered to be only approximate, especially on the
    faint end, because of a lack of photoelectric standards there.]]></p:para>
