Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

    Description:
        The catalogue contains 4174 stars in the Northern Milky Way, in the
        range 32°<l<214°, -10°<b<+10°, having the H line in
        emission.

        The HBH list (main list, Schmidt camera Hamburg-Bergedorf, red plates
        taken in the years 1964-70) contains 1979 objects partly identical
        with those in other lists of H emission-line stars given in the
        literature up till 1994.

        Non-stellar objects (e.g. HII regions, planetary nebulae) have not
        been included in this catalogue except for those objects containing
        central stars which have the H line in emission, and also for some
        doubtful cases.

    Note (1):
         The number if made from the page header (1 to 70) and a running
         number on the page (1 to 60).
    Note (2): colour system given in the literature:
       (blank) = photoelectric in the V system,
            B  = photoelectric in the B system,
            v  = visual or photovisual,
            p  = photographic,
            r  = red or photored,
            m  = spectral region not known,
            e  = estimated on our Schmidt-camera plates (A10) according to
                 the classification of the spectra of HBH stars (see Section 2)
    Note (3):
        "V" following the magnitude means variable star; the given brightness
        corresponds to that of the maximum. We confirmed the variability of
        many stars and found several new variable stars.
    Note (4):
        The 6-digit number represents the Declination in degrees, followed
        by the Right Ascension in hours and minutes, of the center;
        for instance, 600000 means +60°, 00h00m POSS plate.
    Note (5):
        S (at the end, but not part of the designation) indicates an object
        having a suspected H{alpha} emission line or perhaps a non-stellar
        object. There are two reasons for a designation as ``suspected'':
          a) the contrast between the H{alpha} emission line and the
             continuum in the neighbourhood is small,
          b) the object may not be a stellar one: e.g. the object is a
             compact HII region, a knot of the large HII region or a
             planetary nebula
    Note (6):
        Classification of the spectrum of HBH stars on the Schmidt camera
        long-exposed (30 min) red plates.
         * H{alpha} emission line is (first character):
           1 = very faint,
           2 = faint,
           3 = moderate,
           4 = strong,
           5 = overexposed;
         * continuum is (second character):
         "-" = invisible or very faint,
           A = faint,
           B = moderate,
           C = strong,
           D = overexposed,
        * "-- " is found when no classification of the spectrum in the above
           system possible,  mainly because  H emission line visible  on
           short-exposed (<30 min) plates only, or because of variability;
    Note (7):
        Existence of the finding chart in Part 2:
        1 = one chart,  2 = two charts.
        See the range of RA given on Plates.
