My research time this weekend was spent closely reading and commenting on Maller's draft of a paper about empirical determination of inclination corrections, or the effects of internal absorption in galaxies by dust that can be detected by observing similar galaxies at different inclinations to the line of sight. Maller's approach is unusual, because he simply tries to find the corrections such that the distribution of corrected galaxy properties (and more than just the spectrum can be affected) is independent of axis ratio (the observable most closely related to inclination).
