Launhardt, R., Henning, Th., Queloz, D., Quirrenbach, A., Bakker, E. J., Baumeister, H., ...
Deriving unambiguously the orbital parameters and masses of extrasolar planets requires at least 2-dimensional information on either the positions or motions of the planet directly (currently out of...

Diffraction-limited CCD imaging with faint reference stars (2002)
Tubbs, R. N., Baldwin, J. E., Mackay, C. D., Cox, G. C.
By selecting short exposure images taken using a CCD with negligible readout noise we obtained essentially diffraction-limited 810 nm images of faint objects using nearby reference stars brighter...
Diffraction-limited 800 nm imaging with the 2.56 m Nordic optical telescope. (2001)
Baldwin, J. E., Tubbs, R. N., Cox, G. C., Mackay, C. D., Wilson, R. W., Andersen, M. I.
A quantitative assessment is presented of diffraction-limited stellar images with Strehl ratios of 0.25-0.30 obtained by selection of short-exposure CCD images of stars brighter than +6 m at 810 nm...

Sub-electron read noise at MHz pixel rates (2001)
Mackay, C. D., Tubbs, R. N., Bell, R., Burt, D., Moody, I.
A radically new CCD development by Marconi Applied Technologies has enabled substantial internal gain within the CCD before the signal reaches the output amplifier. With reasonably high gain,...
