HIPASS Catalogue detection HIPASSJ0000-07

Notes:

• 1 - RA-Dec image of HIPASS detection. Channel maps are summed over the velocity range that just includes the emission. The total image size is 2x2 degrees.
• 2 - As 1, but here the search box that is used to fit the parameters is indicated and a ellipse shows the FWHM of a Gaussian fitted to the detection.
• 3 - As 2, but showing the full spatial range of the cube in which the detection was found. This image is 8x8 degrees for cubes around the equatorial strip, and progressively smaller for more southern cubes.
• 4 - Position velocity cut along the RA axis. Typically 3000 km/s around the detection are shown.
• 5 - As 4, but here the extent of the search box from image 2 is indicated, as well as the velocity range that is used for summing the moment maps.
• 6 - As 5, but now showing the full spectra range
• 7 - Spectrum of the detection obtained by treating the detection as a point source (except for extended sources, see Paper I). The baseline fit is shown by a green curve. Vertical lines show the velocity range used for obtaining the moment maps.
• 8 - As 7, but showing the velocity width at 20% and 50% of the peak flux. Crosses show the results of the width minimization prodedure and circles correspond to the width maximization procedure (see Paper 1).
• 9 - As 7, but showing the full spectral range.
• 10 - As 7, but now with baseline subtracted.
• 11 - As 9, but now with baseline subtracted.
• 12 - As 11, but without Hanning smoothing.
