Abstract The brightness distribution of diffuse soft X-rays in the pulse height range 0.15–0.3 keV (L-band) and 0.5–0.8 keV (M-band) are obtained over a quarter of the sky centered at the galactic anticenter with 1.5 μm polypropylene window proportional counters on board a sounding rocket. In theL-band three enhanced regions are noticed on the map. They coincide with the northern and southern Hi holes and the inner part of the galactic radio Loop II. In the northern Hi hole theN H dependence of theL-band flux and the hardness ratioM/L can be fitted with a local hot plasma model with the absorption by a low velocity neutral hydrogen gas (|V|〈25 km s−1) along the line of sight. The X-ray feature of Loop II is similar to that of Loop I. In the lowN H region (〈3×1020 H atoms cm−2) theM/L value is lower than 0.3, whereas it varies in the range 0.1–0.4 at low latitudes (|b|〈300). This fact seems to be interpreted in terms of a model that a number of hot plasma clouds contribute to X-ray emission.
