ALMA CO(1-0) data for IRAS F17207−0014. Top left: moment-zero map. Overplotted are contours for outflow in the range [−900, −500] km s−1 (blue, contours at [0.6, 0.9] mJy beam−1). Top right: nuclear spectrum. The spectrum is decomposed into four Gaussians, three for the host line profile and one for outflow (green). The black line includes all four Gaussian components. Center left: center positions and their errors, from UV fitting a Gaussian model to individual velocity channels. Center and bottom right: position-velocity diagrams. Fast outflowing molecular gas is seen on the blue side only. PA +160° is the orientation of the blue outflow component measured in higher-resolution CO(2-1) data by García-Burillo et al. (2015), our lower-resolution data are consistent with this by placing the blue outflow slightly south of the nucleus (see center left panel). PA −50° is the approximate orientation of the central arcsecond-scale gas disk.
