Planetary nebulae are the remnants of low-to-middle mass stars. ... These so-called post-AGB stars are in an intermediate stage of evolution between the AGB and planetary nebulae. ... By studying the post-AGB stars we may be able to determine what causes the complicated structures seen in some planetary nebulae. To investigate this question, we have selected a well-defined sample of 86 post-AGB stars from a previous study of OH 1612-MHz maser sources in the Galactic plane (Sevenster et al., ...

... There will likely be science programs that do not fit exactly into any one of these categories, or that have different requirements. Very Short Exposures : If each target is observed for less than a few minutes then the extra overhead for dithering can significantly impact the overall S/N, thus offsetting any advantages gained by dithering . ... Even if sub-pixel dithering is not necessarily required, dithering each exposure by an integer pixel shift reduces the impact of hot pixels. ...
