2. WFPC2 Instrument Handbook Update
... To be read in conjunction with Section 7.6 of the WFPC2 Instrument Handbook , Version 4.0 Dithering is the act of displacing the telescope between observations either on integral pixel scales (to assist in removing chip blemishes such as hot pixels) or on sub-pixel scales (to improve final image resolution). ... In particular, at the time of the last writing, our experience in removing cosmic rays from singly dithered data (i.e., only one image per pointing) was quite limited. ...

7. The contour method of calculating source region shape
... Meta Index / Home Page / Description / Specifying source region shapes . When radiusstyle =`contour', the task calculates the source region shape as an elliptical locus which approximates the contour of the PSF at a given flux value. ... Clearly, in order to calculate the shape of such a flux contour, it is necessary firstly to normalize the PSF to the source brightness and secondly to determine the flux level (in `brightness' units per pixel) at which to find the contour. ...

11. Fabry-Perot Images of Spiral Galaxies
The first series of images refers to NGC 1672, a barred spiral. We present a gray scale V-band image to show the overall morphology, followed by an intensity map in H-alpha which shows how the H II regions are distributed, followed by the velocity map. ... Different colors refer to different velocities as the galaxy is rotating. ... The following image is an H-alpha intensity map of the spiral galaxy NGC 1292. ... This next image is an H-alpha intensity map of the spiral galaxy NGC 1406. ...
