The data available here have been presented in my papers on cataclysmic variables. The photometric observations are presented as text files containing HJD (sometimes minus 2400000) and differential magnitude (warning: some light curves are not given in HJD but in JD with the heliocentric correction given in the second column). The spectroscopy is presented in the native format of the spectral reduction, analysis and storage package I use, molly, written by Tom Marsh. Please contact me if you would like spectra in other formats (ascii, FITS).

The INT, WHT and LT (Liverpool Telescope) data were taken by various members of the University of Warwick astrophysics group as part of the 2004 International Time Project at La Palma.
These data are described in Southworth et al. (2007, MNRAS, 378, 635).

These data were taken as part of a collaborative effort by various members of the University of Warwick astrophysics group.
KUV 23182+1229 was investigated as a possible ultra-compact binary due to apparent helium II emission at 4686 Å in an old classification spectrum. KUV 23061+1007 was also observed because the authors of the original paper managed to get completely confused between the two objects.
It turns out that KUV 23182+1229 is a quasar at a redshift of 0.665, and the emission near 4680 Å is actually due to the magnesium 2800 Å quasar feature. As expected, KUV 23061+1007 is a bog-standard white dwarf of type DA. These results were published in Southworth et al. (2007, IBVS, 5775).
