ABSTRACT:We present a study of the distribution of interstellar dust and H_I, using 100-mum and 21-cm measurements, for two regions of very low total
column density.
We find that down to the spatial resolution of the HI data (12
arcmin), there is good agreement between dust and neutral gas
features.
Although the 100-mum data show substantial variance on scales corresponding to
the detector resolution (5 arcmin), it is found that this is consistent
with that expected from an extrapolation of the 100-mum luminosity
function to faint (<1 Jy) sources.
We find no evidence for structure in the
cirrus on scales of ~5-10 arcmin.
The effect on the transmission of soft
X-rays arising from such structure that may be present is found to be
negligible.
