1. An IRAF-Independent Interface for Spatial-Region Descriptors
... To move toward open analysis software, we plan to make the PROS regions subsystem available from processes outside of IRAF. We also plan to make the region descriptor parsing system available for purposes beyond the creation of masks, such as an interface to an image display program, accepting a region descriptor and generating commands to display the region on an image. ... Anticipating two kinds of new requirements, we reconsidered the design of the PROS region descriptor processing subsystem. ...

4. Visitors Tourists -- The AO Optical Laboratory
At Arecibo we have a variety of optical instruments that we use to study terrestrial airglow emissions. ... As a complement to the airglow instrumentation we also maintain a set of optical instruments, called lidars, used for "active" remote sensing of the atmosphere. That is, we generate our own source signal using lasers and measure the characteristics of the light scattered back from the atmosphere. ... An operations manual for the Optical Laboratories is currently under major revision. ...

9. ESO - Thesis Topic: Planetary Nebulae and HII regions in the Elliptical Galaxy
... Science Users Information > Science Activities > PhD Thesis Topics offered by ESO Faculty Members > Thesis Topic: Planetary Nebulae and HII regions in the Elliptical Galaxy NGC 5128 . ... NGC 5128 is the closest example of a giant early type (elliptical or S0) galaxy. Although often dubbed as a peculiar elliptical galaxy since it has a dust lane with recent star formation and an active galactic nucleus, the majority of early type galaxies have similar structures as revealed by recent surveys. ...
