Abstract
We present first results of the H2O Southern Galactic Plane Survey (HOPS), using the Mopra Radio Telescope with a broad-band backend and a beam size of about 2 arcmin. We have observed 100 deg2 of the southern Galactic plane at 12 mm (19.5-27.5 GHz), including spectral line emission from H2O masers, multiple metastable transitions of ammonia, cyanoacetylene, methanol and radio recombination lines. In this paper, we report on the characteristics of the survey and H2O maser emission. We find 540 H2O masers, of which 334 are new detections. The strongest maser is 3933 Jy and the weakest is 0.7 Jy, with 62 masers over 100 Jy. In 14 maser sites, the spread in the velocity of the H2O maser emission exceeds 100 km s-1 In one region, the H2O maser velocities are separated by 351.3kms-1. The rms noise levels are typically between 1 and 2Jy, with 95 per cent of the survey under 2Jy. We estimate completeness limits of 98 per cent at around 8.4 Jy and 50 per cent at around 5.5 Jy. We estimate that there are between 800 and 1500 H2O masers in the Galaxy that are detectable in a survey with similar completeness limits to HOPS. We report possible masers in NH3 (11,9) and (8,6) emission towards G19.61-0.23 and in the NH3 (3,3) line towards G23.33-0.30.

We have observed 100 deg<sup>2</sup> of the southern Galactic plane at 12 mm (19.5-27.5 GHz), including spectral line emission from H<sub>2</sub>O masers, multiple metastable transitions of ammonia, cyanoacetylene, methanol and radio recombination lines. In this paper, we report on the characteristics of the survey and H<sub>2</sub>O maser emission. We find 540 H<sub>2</sub>O masers, of which 334 are new detections. The strongest maser is 3933 Jy and the weakest is 0.7 Jy, with 62 masers over 100 Jy. In 14 maser sites, the spread in the velocity of the H<sub>2</sub>O maser emission exceeds 100 km s<sup>-1</sup> In one region, the H<sub>2</sub>O maser velocities are separated by 351.3kms<sup>-1</sup>. The rms noise levels are typically between 1 and 2Jy, with 95 per cent of the survey under 2Jy. We estimate completeness limits of 98 per cent at around 8.4 Jy and 50 per cent at around 5.5 Jy. We estimate that there are between 800 and 1500 H<sub>2</sub>O masers in the Galaxy that are detectable in a survey with similar completeness limits to HOPS. We report possible masers in NH<sub>3</sub> (11,9) and (8,6) emission towards G19.61-0.23 and in the NH<sub>3</sub> (3,3) line towards G23.33-0.30.</div></front></TEI><inist><standard h6="B"><pA><fA01 i1="01" i2="1"><s0>0035-8711</s0></fA01><fA02 i1="01"><s0>MNRAA4</s0></fA02><fA03 i2="1"><s0>Mon.

The rms noise levels are typically between 1 and 2Jy, with 95 per cent of the survey under 2Jy. We estimate completeness limits of 98 per cent at around 8.4 Jy and 50 per cent at around 5.5 Jy. We estimate that there are between 800 and 1500 H<sub>2</sub>O masers in the Galaxy that are detectable in a survey with similar completeness limits to HOPS. We report possible masers in NH<sub>3</sub> (11,9) and (8,6) emission towards G19.61-0.23 and in the NH<sub>3</sub> (3,3) line towards G23.33-0.30.</s0></fC01><fC02 i1="01" i2="3"><s0>001E03</s0></fC02><fC03 i1="01" i2="3" l="FRE"><s0>Plan galactique</s0><s5>26</s5></fC03><fC03 i1="01" i2="3" l="ENG"><s0>Galactic planes</s0><s5>26</s5></fC03><fC03 i1="02" i2="3" l="FRE"><s0>Maser</s0><s5>27</s5></fC03><fC03 i1="02" i2="3" l="ENG"><s0>Masers</s0><s5>27</s5></fC03><fC03 i1="03" i2="X" l="FRE"><s0>Raie émission</s0><s5>28</s5></fC03><fC03 i1="03" i2="X" l="ENG"><s0>Emission line</s0><s5>28</s5></fC03><fC03 i1="03" i2="X" l="SPA"><s0>Raya emisión</s0><s5>28</s5></fC03><fC03 i1="04" i2="X" l="FRE"><s0>Transition métastable</s0><s5>29</s5></fC03><fC03 i1="04" i2="X" l="ENG"><s0>Metastable transition</s0><s5>29</s5></fC03><fC03 i1="04" i2="X" l="SPA"><s0>Transición metaestable</s0><s5>29</s5></fC03><fC03 i1="05" i2="3" l="FRE"><s0>Ammoniac</s0><s5>30</s5></fC03><fC03 i1="05" i2="3" l="ENG"><s0>Ammonia</s0><s5>30</s5></fC03><fC03 i1="06" i2="3" l="FRE"><s0>Méthanol</s0><s2>NK</s2><s5>31</s5></fC03><fC03 i1="06" i2="3" l="ENG"><s0>Methanol</s0><s2>NK</s2><s5>31</s5></fC03><fC03 i1="07" i2="X" l="FRE"><s0>Raie recombinaison radio</s0><s5>32</s5></fC03><fC03 i1="07" i2="X" l="ENG"><s0>Radio recombination line</s0><s5>32</s5></fC03><fC03 i1="07" i2="X" l="SPA"><s0>Raya recombinación radio</s0><s5>32</s5></fC03><fC03 i1="08" i2="3" l="FRE"><s0>Galaxies</s0><s5>33</s5></fC03><fC03 i1="08" i2="3" l="ENG"><s0>Galaxies</s0><s5>33</s5></fC03><fC03 i1="09" i2="3" l="FRE"><s0>Formation stellaire</s0><s5>34</s5></fC03><fC03 i1="09" i2="3" l="ENG"><s0>Star formation</s0><s5>34</s5></fC03><fC03 i1="10" i2="X" l="FRE"><s0>Structure galaxies</s0><s5>35</s5></fC03><fC03 i1="10" i2="X" l="ENG"><s0>Galaxy structure</s0><s5>35</s5></fC03><fC03 i1="10" i2="X" l="SPA"><s0>Estructura galaxias</s0><s5>35</s5></fC03><fN21><s1>283</s1></fN21><fN44 i1="01"><s1>OTO</s1></fN44><fN82><s1>OTO</s1></fN82></pA></standard></inist><affiliations><list><country><li>Allemagne</li><li>Australie</li><li>Chili</li><li>France</li><li>Royaume-Uni</li><li>États-Unis</li></country><region><li>Angleterre</li><li>Yorkshire-et-Humber</li></region><settlement><li>Leeds</li></settlement><orgName><li>Université de Leeds</li></orgName></list><tree><country name="Australie"><noRegion><name sortKey="Walsh, A J" sort="Walsh, A J" uniqKey="Walsh A" first="A.
