We present a consistent set of measurements of electron drift velocities an
d Lorentz deflection angles for all noble gases with methane and ethane as
quenchers in magnetic fields up to 0.8 T. Empirical descriptions are also p
resented. Details on the World Wide Web allow for guided design and optimiz
ation of future detectors. (C) 1999 Elsevier Science B.V. All rights reserv
