averaging the channels and using the same two FOVs as at 5 GHz. The imaging was also performed using only the baselines shorter than 15 M$\lambda$, which resulted in a beam size of 33 mas $\times$ 27 mas.

Results
=======

A total of thirty-one X-ray sources are detected by *wavdetect* in the 0.3–10 keV band, of which fifteen lay within the D25 ellipse of the host galaxy. The location of the fifteen detected sources is shown in Fig. \[fig1\], and their position, observed flux, and 0.3–10 keV band luminosity are provided in Table \[table1\].

![Digitized Sky Survey (@1990AJ.....99.2019L) image of NGC4088. The position of the fifteen sources detected by *wavdetect* in the 0.3–10 keV band within the D25 ellipse of NGC4088 are marked with orange circles of radius 3 arcsec. The position of the ULX is marked with a white circle.\[fig1\]](sourcesD25DSS_v2.pdf)
