in which the target was stationary. The “worm” appears to be present in every exposure and, at this time, there is no explanation for it. Because of the temporal changes in the strength and position of the worm, CalFUSE cannot correct target fluxes for its presence. Here we take particular care to discard the portion of the spectrum where the so-called *worm* ’crawls’, which deteriorates LiF1 longward of 1125Å . Because of this the $1182 - 
1187$Å region is lost. We then rescale and combine the spectra. When we combine, we weight according to the area and exposure time for that channel and then rebin onto a common wavelength scale with a $0.1$Å, $0.2$Å, and $0.5$Å  resolution.

In the observing log given in Table 2, the entries are by column: (1) gives the target, (2) [*[FUSE]{}*]{} spectral data ID, (3) the aperture used, (4) the date and time of observation, (5) the (good) exposure time in seconds, (6) central wavelength, and (7) S/N.

The [*[FUSE]{}*]{} spectra for the three systems, UU Aql, BV Cen and CH Uma are displayed in Figures 1, 2, and 3 respectively. A quantitative sense of the relative data quality is provided by the signal to
