Description:
    The results of a survey of SiO emission using the 15-m SEST and the
    20-m Onsala telescope are presented in two tables. The sample contains
    altogether 369 objects including 270 H2O masers, 19 OH masers and 62
    IRAS sources with colours typical for ultracompact HII regions. The
    remaining target sources consist of dust continuum peaks a CS emission
    peak near H2O masers (12) and Herbig-Haro objects (6). The entries are
    arranged according to increasing right ascension.

Note (2): H2O maser or sometimes OH maser, in which case clearly indicated

Note (3): FW = V_max - V_min

Note (4): The cloud velocity refers usually to the velocity of the
    associated dense core as estimated from CS data. When the latter has
    not been available, a radial velocity determined from NH3 or CO
    observations has been used.

    If no molecular line measurements has been found in the literature we
    have used for the kinematic distance estimate the peak radial velocity
    of the SiO(J=2-1) line from the present survey or the peak velocity of
    the associated maser. In this case, there is no velocity cloud data.

Global Notes:

Note (G1): When no reference is given the distance is a kinematic distance
    calculated from the cloud velocity by using the galactic rotation
    curve determined by Brand & Blitz (1993, Cat. J/A+A/275/67) for
    R0=8.5kpc and θ0=220km/s.

    For sources in the first and fourth quadrants with a distance
    ambiguity the near kinematic distance was assumed.

    When no value is given when no solution has been found with the
    kinematical model, nor any reference to a photometric distance.
