All Tables

Table 1: Positions of the ULXs and their 0.3-8 keV X-ray luminosities. In the fields with only one ULX, the pointing center is the ULX. The field of NGC 4736 was centered in the middle of both sources. A * in front of the ULX name denotes the pointing center.
Table 2: Observing dates of the different epochs. The sources are observed in two groups. The first group consists of M 33, NGC 2403 and M 82, while NGC 4736, NGC 5204 and the two FOVs in NGC 5457 belonging to the second group.
Table 3: rms flux values for the different FOVs. Besides the rms of each epoch we give the rms value for map of the combined dataset. All values are given in $\mu$ Jy. For a discussion on M 82 see Sect. 3.2.1.
Table 4: Radio detections near detected X-ray point sources in M 82. A flux of 1 mJy corresponds to $3 \times 10^{18}$ W/Hz at the distance of M 82.
Table 5: Other radio detections.
Table 6: The radio power of our sample for continuous emission and flares. The radio detections in M 82 are probably SNRs while in NGC 4736 we probably detect the nucleus of the galaxy. For all other sources we present upper limits for continuous emission over all epochs and flares. The distances are taken from Tully (1988).
Table A.1: Radio flux and beam size of the double source in NGC 4736.
