... else

with the exceptions of IGR J10101-5654, J18214-1318, J16287-5021, and J19267+1325 whose Chandra positions have very recently been published by Tomsick et al. (2008b,a)

... power-law

Note that we chose to use a simple power-law rather than the more sophisticated models usually used to fit CV spectra in order to compare the XRT spectral parameters to those mentioned in the literature. In particular, Götz et al. (2006) showed that the extrapolation at hard X-rays of spectrum obtained with ROSAT was compatible with the INTEGRAL/IBIS one. A discussion of the emission processes at work in CVs is beyond the scope of this paper.

... position

uvotcentroid obtains mean coordinates by running a series of Monte-Carlo simulations of the source's pixel distribution on a $20 \times 20$ $^{\prime\prime}$ sub-image centred on the best position
