The quantity of dust in a spiral disk can be estimated using the dust's typical emission or the extinction of a known source. In this paper we compare two techniques, one based on emission and one on absorption, applied to sections of 14 disk galaxies. ... Hence, they depend differently on the average number and optical depth of ISM structures in the disk. The small-scale geometry of the cold ISM is critical for accurate models of the overall energy budget of spiral disks. ...

. Figure 3. SOHO/EIT derotated 6-hour difference images of the 14 July 2000 event in four diverse-temperature lines 171, 195, 284, and 304 . For each line, the 13 UT heliogram is subjected to the suppression of the `snowstorm' produced by energetic particles, and only dimmings (i.e. structures of negative resulting intensity) are shown. Different appearance of the images is due to different exposure times.
