Telescope Archive for Pool and AstronomerS TAPAS
TAPAS provides a complete, homogeneous, and searchable database of the header information of all astronomical observations conducted at the IRAM 30m telescope since February 01, 2009. TAPAS has been a joint IAA-CSIC/IRAM effort over the past 3 years since 2005, partially funded by the Spanish ministry via grant AYA2005-07516-C02. TAPAS will contain more than 200 header variables for each observational scan, encompassing
- information on the observing setup (source, frequency, observing mode, etc.),
- information on the project (PI, Title, etc.),
- the status of the system at the time of the observations (telescope, receiver, backend, weather, etc.),
- and also the results of calibrations, of pointing and focus scans.
It is planned that TAPAS contains header information of all astronomical data taken after 1.2.2009.
TAPAS Data Policy
by Carsten Kramer & Pierre Cox (19-Nov-2008)
Header Data
To preserve the confidentiality of some pieces of information, a subset of the astronomical header data will be made accessible with a delay of 12 months from the end of the scheduling semester in which the project was observed. TAPAS will provide access via web interfaces and search tools, and a Virtual Observatory facility for query and retrieval of header data. For each scan, the subset will encompass the project number, source name and position, date of observations, LST time, integration time, observing mode, and sky frequency. IRAM staff will have immediate and unrestricted access to all header data.
Astronomical Data
TAPAS does not contain any astronomical heterodyne or bolometer data. However, TAPAS provides the possibility to link the header data of individual scans to FITS files containing the uncalibrated astronomical data. Access rights to any astronomical data in TAPAS depend on the project: In general, the proprietary period is indefinite. The PI and IRAM decide when to make astronomical data public. For large programs, access to all data will be granted after a 18 months proprietary period. The proprietary period starts when the last observations of a given project are finished.
