Velocity field of 3C 249.1 EELR
Velocity field of 3C 249.1 EELR derived from the [O III] 5007 region in the GMOS/IFU data cube. The three columns, from left to right, are line intensity, radial velocity (relative to that of the nuclear narrow line region) and velocity width maps. To separate different clouds that are present along the same line of sight, the velocity field is shown in three separate velocity bands (−460 to −300 km/sec, −230 to +150 km/sec and +180 to +590 km/sec from the top row to the bottom row). The rectangles delineate the 3.′′5 x 5′′ FOV of GMOS/IFU. Pixels are 0.′′2 squares. The crosses indicate the position of the quasar, which has been removed from the datacube.
