4 Comparison of the ALMA and Herschel - ESO

calibration files and to a pipeline for quick looks as well as a package for complete data
reduction. Ideally the pipeline products would be publication quality images.
ESO: There is a need to carry out finding surveys for extragalactic/galactic sources using
single dishes such as APEX with the LABOCA bolometer camera system.
For the time when both instruments are available, an efficient approach would involve a
process where ESO reacts quickly to the need for follow-ups to Herschel data. For ALMA it
would be useful to allocate observing time as soon as possible to measure variable sources,
newly discovered sources, peculiar objects or in general to perform follow-ups of selected
fields both in line and continuum that are as complete as possible.
Both Organisations: The most pressing need is to coordinate large surveys that are planned
in Herschel guaranteed time. There should be a series of dedicated conferences/workshops
once the guaranteed time plans for Herschel are complete. These workshops should continue
during the lifetime of Herschel. There may be difficulties in arranging for any coordination
that involves large blocks of ALMA observing time, since the policies and organisation of
ALMA Time Allocation Committees are in the discussion phase.
