Focussing

A sequencer command 'focus-auto' has been developed to analyse focus images for ALFOSC, MOSCA and StanCam taken with corresponding sequencer commands. The calculated best focus value is reported on screen together with various statistics.

All the default focus values are now entered in our data base system, while the web-pages have been changed to list the values from the data base instead of specific numbers. Also, where appropriate, sequencer scripts have been changed to use these data base values. In this way, if there is a change to any default focus value (e.g., after an aluminisation) this only needs to be changed in the data base.
