to final data reduction,seeks innovative uses of the telescope |
| configurer |
understands thoroughly at least some significant proportion of the
telescope's capabilities and the actual effect various devices' settings
will have on the system and the resulting data, regular user of the
SuD, generates useful setups of the telescope |
