================================================================================
ADC_Keywords: Planetary nebulae

Description:
    The catalog provides a list of data concerning all known planetary
    nebulae.  The total number is 1455, including 1036 listed in the
    Perek and Kohoutek (PK) catalog (1967), and including doubtful cases.
    The additions come from Sanduleak (1975, 1976), Acker and Marcout
    (1977), Weinberger (1977), Peterson (1977), Kohoutek (1978),
    Stephenson (1978), Allen (1979), Murdin et al. (1979), van den Bergh 
    (1979), and Purgathofer and Weinberger (1980).  The catalog includes 
    PK numbers, equatorial coordinates, visual magnitudes, angular sizes, 
    mean radial velocities, magnitudes of central star, and expansion 
    velocities of the planetary nebulae.

Note on PK: 
    Perek-Kohoutek (PK) number or number of the same form.  This
    catalogue contains 1455 records.  The records are ordered by right
    ascension (bytes 10-17).  Note: references are given after Section 1
    above.  
      1-3  Galactic Longitude, (system II) in I3 degrees.
      4-9  Galactic Latitude, (system II) in F6.2 degrees.  In all
           cases butt one, byte 9 is blank.  In that case, 
           PK 358 + 3.10 (zero in byte 9) is differentiated from 
           PK 358 + 3.1.

Note on RAh, DEd:
    Equatorial coordinates (1950).  These agree with the radio 
    coordinates of Higgs (1971) to within 0.01 minutes of right
    ascension and 0.1 arcminutes of declination.

Note on V:
    Visual magnitude of planetary nebula, integrated over its
    surface.  A blank field (value 0.0) indicates no data.

Note on morph:
    Morphology indicator: "<" for star-like appearance, ">" for
    fainter spherical envelope (Higgs 1971) or else blank. 
    Blank field indicates no data.

Note on Diam:
    Average diameter of the brightest part of the planetary nebula,
    in seconds of arc, angular size. Blank field indicates no data.

Note on Vstar:
    Magnitude of central star either from Kaler (1978) (B value), 
    from Aller (1976), or the average value from Perek and Kohoutek 
    (1967).

Note on vexp:
    Expansion velocity of the planetary nebulae (Acker 1976, Johnson
    1976, Alloin et al.  1976).
