Christine Clement's Research at Las Campanas, Chile

I began observing with the University of Toronto's telescope in Chile in 1972 and continued until 1997 when the facility was closed. Having access to one telescope for such a long time made it possible for me to make important contributions to the study of variable stars in globlar clusters, particularly RR Lyrae variables.

Initially I used photographic plates to record the data. This involved spending the nights in the dome and the days in the dark room. Then when I returned to Toronto, hours were spent with measuring machines.

Fortunately, developments in technology since the 1970s have made data acquisition much more efficient.

Beginning in the early 1990s, I switched to CCD detectors. With these electronic devices, the data can be transferred directly from the telescope to a computer. It is no longer necessary to spend hours developing and measuring photographic plates.
