vo@astron.nlImages The The VO @ ASTRON's sitewide SIAP version 2 service publishes all the images published through the site. For more advanced queries including uploads, all this data is also available through ObsTAP.https://vo.astron.nl/__system__/siap2/sitewide/infoserved-byThe VO @ ASTRON TAP servicehttps://vo.astron.nl/__system__/siap2/sitewide/siap2.xml?GETapplication/x-votable+xmlPOSA spatial constraint using SIAPv2 CIRCLE, RANGE, or POLYGON shapes and respective values in decimal degrees.charBANDWavelength interval that should intersect with the dataset coveragerealTIMETime interval that should intersect with the dataset coveragerealPOLPolarisation states as per Obscore (i.e., from the set I Q U V RR LL RL LR XX YY XY YX POLI POLAcharFOVLower and upper bound for the field of view of the observationdegrealSPATRESLower and upper bound for the spatial resolution of the image(s)degrealSPECRPLower and upper bound for the spectral resolving power λ/Δλ in spectrally resolved observationsrealEXPTIMELower and upper bound for the integration times of the observationsrealTIMERESLower and upper bound for the (absolute) resolution on the time axissrealIDA dataset identifier to match. Note that contrary to the SIAP v2 REC, we do not compare the IVOIDs case-insensitively. This should not be an issue if you got the IVOID from this service. For IVOIDs obtained in other ways, you may need to use ILIKE or a similar facility through ObsTAP.charCOLLECTIONA name of a data collection within the service (use ObsTAP to find out the possible values).charFACILITYA name of a facility (usually a telescope) used to make the observation.charINSTRUMENTA name of an instrument used to acquire the data.charDPTYPESelect either image or cube.charCALIBCalibration level of the data (0=raw data .. 3=processed science-ready data)integerTARGETA name of an observation target.charFORMATMedia type (like image/fits) or similar of the data product searchedcharRESPONSEFORMATFile format requested for output.meta.code.mimecharMAXRECMaximum number of records returned.
