| Abstract: |
The Telescope Data Center at Smithsonian Astrophysical Observatory
supports observations and data flow from the optical telescopes of the
Harvard-Smithsonian Center for Astrophysics. With a limited amount
of manpower, we handle the entire process from instrument operations to
the data archiving and scientific reduction, which allows us to avoid
many of the difficulties other data centers encounter arising from the
incompatibility of on the instrument and data processing sides.
We use telescope control software and data reduction pipelines developed
inside our unit which also helps us to ensure the consistency of data
products at different stages of processing. Presently we are working on
a data archive solution using PostgreSQL and GAVO DaCHS which will allow
us to: (1) distribute the raw data to PIs on a timescale of days from
observations; (2) feed the data reduction pipelines automatically; (3)
distribute reduced science ready data to the PIs; (4) provide access to
raw and processed data products using Virtual Observatory interfaces
such as ObsTAP, SIAP, SSAP after the proprietary period of the data has
expired; (5) maintain a searchable record of all astronomical sources
observed by the instruments, along with a catalog of basic observing
conditions and telescope/instrument status associated with each
exposure. I will present the data archive prototypes for the MMIRS
multi-object spectrograph. Our operations model can be scaled up and
adopted by large optical observatories. |
