Absorption line profile asymmetries in ellipticals with peculiar core kinematics, and their role as diagnostics of mergers, are analyzed using self-consistent numerical merger models. The remnants of mergers involving a denser secondary component show asymmetric line-of-sight velocity distributions at their cores. Skewness is negative where the

CCD imaging of low-luminosity radio galaxies to detect the optical counterparts of radio jets is described in terms of the surface-photometry procedure and the results for two galaxies. The galaxies have low-power radio jets at the arcsec scale and appear to be interacting with companion galaxies. Interfering images are removed, and isophotal

The way in which the effect of the instrumental polarization of a spectrograph can distort the shape of the intensity profiles in sunspots is shown empirically. A spectral region around a magnetically sensitive line and a sunspot away from the disk center were chosen. The resulting limitations which arise when trying to derive physically meaningful

In the present comparative study of published values for the scale lengths of spiral galaxies' exponential disks, the average value of the discrepancy for more than 120 galaxies is 23 percent, with a standard deviation of 20 percent. Neither systematic trends nor correlations of discrepancies with such galaxy parameters as morphological type, arm
