Left: rotation map showing a model Keplerian rotation pattern for AT Pyx’s gas content. Right: residual, i.e. the rotation map subtracted from the peak velocity image, showing deviations in the rotation patterns from a Keplerian velocity field. We note that the high residuals (dark red) could indicate some level of pollution from the ¹²CO signal in the surrounding globule gas. In these images north is up and east is to the right.
