Equations (1) and (2) were set incorrectly in the published version of this paper; the equivalence appearing in the denominator should in fact be the final value on the right-hand side. The correct forms of these equations are:AKs=(EH-K)/((λH/λKs)-1.53-1)=1.55-0.21/((1.662/2.159)-1.53-1)=2.73, (1)andAKs=(EJ-K)/((λJ/λKs)-1.53-1)=4.62-0.89/((1.2352

Aims.We report the discovery of five new dwarf novae that were spectroscopically identified in the Hamburg Quasar Survey (HQS), and discuss the properties of the sample of new dwarf novae from the HQS.Methods.Follow-up time-resolved spectroscopy and photometry have been obtained to characterise the new systems.Results.The orbital periods determined

In ATEL #871 the fluxes were incorrectly quoted. All the fluxes should be multiplied by 1E-10 in order to obtain the correct values. The quoted luminosities are correct since the right fluxes were used to calculate them. We apologize for any confusion this error might have caused.

Though it is now clear that accretion of dwarf galaxies likely played a prominent role in creating the Milky Way (MW) halo, the chemical abundance patterns of current MW satellites are typically very different than those of halo stars, and the reason for these differences remains a matter of speculation. We propose to test the bridge from dwarf
