An Atlas of FUSE Sight Lines Toward the Magellanic Clouds

We present an atlas of 57 Large Magellanic Cloud (LMC) and 37 Small Magellanic Cloud (SMC) observations obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite. The atlas highlights twelve interstellar absorption line transitions at a resolution of ~15 km/s. These transitions cover a broad range of temperatures, ionization states, and abundances. The species included are OVI, which probes hot (T~3x10^5 K) ionized gas; CIII and FeIII, which probe warm (T~10^4 K) ionized gas; SiII, PII, CII, FeII, and OI, warm neutral gas; and six different molecular hydrogen transitions, which trace cold (T<=500 K) gas. We include Schmidt Halpha CCD images of the region surrounding each sight line showing the morphology of warm ionized gas in the vicinity, along with continuum images near each FUSE aperture position. Finally, we present several initial scientific results derived from this dataset on the interstellar medium of the Magellanic Clouds and Galactic halo.Comment: 29 pages, 6 figures. Complete Atlas of 94 additional images (~800kB each) is available at http://fuse.pha.jhu.edu/~danforth/atlas Accepted to the ApJS March 200

The sound of musicons: investigating the design of musically derived audio cues

Musicons (brief samples of well-known music used in auditory interface design) have been shown to be memorable and easy to learn. However, little is known about what actually makes a good Musicon and how they can be created. This paper reports on an empirical user study (N=15) to explore the recognition rate and preference ratings for a set of Musicons that were created by allowing users to self-select 5 second sections from (a) a selection of their own music and (b) a set of control tracks. It was observed that sampling a 0.5 second Musicon from a 5-second musical section resulted in easily identifiable and well liked Musicons. Qualitative analysis highlighted some of the underlying properties of the musical sections that resulted in ‘good’ Musicons. A preliminary set of guidelines is presented that provides a greater understanding of how to create effective and identifiable Musicons for future auditory interfaces

Name that tune: musicons as reminders in the home

In this paper we argue that Musicons, short samples from pieces of music are a useful way to present private but memorable reminder messages. We investigated accuracy, memorability and response times for short, medium, and long Musicons. User performance on the Musicons was also compared to short spoken reminders. The study consisted of two sessions a week apart. Quantitative measures were augmented with qualitative questions about associations and memories. Overall, participants achieved a high level of accuracy (89%) on the Musicons. Recognition was stable at 90% or better across sessions for users who were able to construct meaningful links between Musicons and the associated tasks. Optimal response times were achieved for medium-length 0.5 sec. Musicons. We conclude that Musicons are a viable option for alarms and notifications that combine the high learnability of Auditory Icons with the more private nature of Earcons
