4. Results

In Table 1 all narrow-line OH sources found are listed. In total there are 202 sources, 90 of which have been identified with known OH-satellite-line masers. The references for previous OH detections are given in Table 2. We visually identified 166 double-peaked (D), 32 single-peaked (S) and 4 irregular (I) sources. A reliable IRAS identification is found for 151 sources.

For each source the table gives an entry number (Col. 1), the OHtex2html_wrap_inline1218 name (Col. 2), a type (D, S, I) identifier (Col. 3), position in J2000 coordinates (Cols. 4, 5), a measure of the error in the positions (Col. 6), the distance from the source to the pointing centre (Col. 7), the peak, stellar and outflow velocities (Cols. 8 to 11), the peak fluxes (Cols. 12, 13), the noise in the field where the source was detected (Col. 14, velocity resolution tex2html_wrap_inline1172), the number of the reference to previous observations if applicable (Col. 15), the name of the nearest IRAS point source (Col. 16) and the distance to this nearest IRAS point source expressed as a fraction of the corresponding IRAS error ellipse (Col. 17). Table 1 can be retrieved from the WWW (http://cdsweb.u-strasbg.fr/Abstract.html).

In Fig. 2 the longitude-latitude diagram and longitude-velocity diagramm are shown for all 202 sources. The spectra for all sources are shown in Fig. 6. They are displayed with tex2html_wrap_inline1222 on either side of the stellar velocity, except for #71 that has an outflow velocity higher than tex2html_wrap_inline1222. The peaks that were detected at the position of the object are marked by dots on top. For source #46 that has a very irregular spectrum, we marked the whole range of detected velocities for the broad peak. The stellar velocities of the sources in this region of the Galaxy have a much smaller spread than those of the sources in the Bulge region (Fig. 3). Therefore, the sidelobe problem (Paper I) is even more prominent. Spectrum #167 shows a particularly clear example of this, where the real peak of the source is almost masked out by a sidelobe from a neighbouring star that has a higher flux density at this position than even the source itself. Another example to be noted is spectrum #55 that has a strong negative sidelobe from source #56. For details on the extraction of the spectra see Paper I.
