Nick Thomas was involved in the data analysis for the Halley Multicolour Camera and took charge of the testing in 1990 which was designed to determine whether HMC was still functional.
You can see some of the HMC scientific publications in our LAPIS area.
Images from Giotto
The HMC data set has been analysed and the results published in book form as an ESA Special Publication. Below, we show a number of pictures from the book in their original digital form.
This area is still under construction but we are hoping to put some archive material about HMC on-line soon.
