Abstract
The ROSAT PSPC spectrum of the Seyfert 2 galaxy NGC 4388 is analyzed, with the aim to better understand the nature of the extended (a few kp c) soft X-ray emission discovered by the ROSAT HRI. Fitting the spectr um with an optically thin thermal model we find evidence for a metal a bundance significantly lower than solar. We therefore argue that the e mission is due at least in part to another component, maybe unresolved emission from compact sources.
