Fig. 2


Calibrated images of the Jupiter in a 35′ × 35′ field, integrated over 20 sub-bands of 195 kHz within the range 166–172 MHz, for five consecutive 2-h intervals (indicated in each panel). The selected subset of baselines provides an angular resolution of 35′′. Pixel size is 5′′. All panels are centered on the target phase direction (in RA/Dec). The belts are resolved near the center of the image, and the beam is displayed in the bottom left corner in yellow. The point source, east of Jupiter, is J020457+114145. Observing time and CML (CML = central meridian longitude in System III) are indicated in each panel. The motion of Jupiter from image to image is clearly visible. The rocking of the main axis of the image of Jupiter is also discernable. The last image is more distorted, due to lower quality data in the last time window.
