E. Marchetti et R. Ragazzoni, COVERAGE WITH THE AUXILIARY TELESCOPES LASER GUIDE STAR TILT RECOVERYTECHNIQUE, Astronomy & Astrophysics. Supplement series, 125(3), 1997, pp. 551-556
Auxiliary telescopes in the neighbourhoods of a main telescope equippe
d with an LGS can provide, in principle, full sky coverage. The auxili
ary telescopes, however, should be able to move around in order to acq
uire a useful natural guide star (NGS), and to track the LGS; comoving
with the scientific target. Detailed expressions and results of numer
ical simulations are given.
