Background
The main focus is on the data analysis pipeline. Using a galaxy from the THINGS survey, to provide an averaged radial profile, normalised to an arbitrary radius. To do so, I first developed an automated method to derive a velocity field, to then derive a tilted-ring model. After this final step the pipeline should have been suitable to be used in a stacking experiment.
The data for this work is Westerbork HI Survey of Spiral and Irregular Galaxies (WHISP) and the Hydrogen Accretion in Local Galaxies survey (HALOGAS) for this analysis. The HALOGAS is a deep H I survey observed with the Westerbork Synthesis Radio Telescope (WSRT). The HALOGAS survey comprises one of the most sensitive interferometric HI observations of galaxies in nearby and in the Local Universe available, reaching a column density of a few 1.0×1019 cm−2 .The HALOGAS is also useful for the study of faint and diffuse emission in and at the outskirts of nearby galaxies.
