Fig. 5
Sensitivity map of the VLBA+GBT observations. The colour bar represents the rms noise values in μJy/beam. The white crosses represent the target positions. White contours were drawn at 3.5, 4.9, 7, and 9.9 μJy/beam. The high rms in the centre of the map is a result of the calibration process not being able to completely minimise the sidelobe level associated with the strong source at this location.
