Abstract:
    We present results from a continuum VLA snapshot survey of the
    galactic plane in the longitude range 0{deg}<=l<=90{deg} at 1.5GHz.
    Observations were taken every 0.5{deg} in longitude at b=0{deg}. Most
    fields are complete to about 30mJy peak flux density. The positions,
    peak, and total flux density of 471 compact sources (<30") have been
    measured. A complete sample of 329 sources is defined. An excess of
    sources above that expected from extragalactic source counts is seen
    for l<40{deg} at all flux-density intervals. We find 86 compact
    sources that are within 2.4arcmin of a source in the recent radio
    recombination-line survey of Lockman (1989ApJS...71..469L) Source
    counts excluding these 86 sources agree with extragalactic source
    counts for all flux-density and longitude intervals. there may only be
    a small number of galactic objects present in this survey that remain
    unidentified as such.

Note (1): Completness limit (uncorrected for primary-beam attenuation and
           bandwidth smearing) corresponding to the field on which the source
           was found.
Note (2): F1=1 if the source is within 15arcmin from the pointing center,
          otherwise F1=0
Note (3): F2=1 if the the uncorrected source peak flux density is greater
           than the completeness limit of the field, otherwise F2=0
Note (4): A: Survey position is less than 2.6' from the source in
              Altenhoff et al. (1979A&AS...35...23A)
          L: Survey position is less than 2.4' from a recombination-line source
              in Lockman (1989ApJS...71..469L)
          I: Interesting IR source found at survey position by
