The VO @ ASTRON SIAP Version 2 Service

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.
A spatial constraint using SIAPv2 CIRCLE, RANGE, or POLYGON shapes and respective values in decimal degrees.
–
Wavelength interval that should intersect with the dataset coverage
–
Time interval that should intersect with the dataset coverage
Polarisation states as per Obscore (i.e., from the set I Q U V RR LL RL LR XX YY XY YX POLI POLA
–
Lower and upper bound for the field of view of the observation
–
Lower and upper bound for the spatial resolution of the image(s)
–
Lower and upper bound for the spectral resolving power λ/Δλ in spectrally resolved observations
–
Lower and upper bound for the integration times of the observation
–
Lower and upper bound for the (absolute) resolution on the time axis
A 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.
A name of a data collection within the service (use ObsTAP to find out the possible values).
A name of a facility (usually a telescope) used to make the observation.
A name of an instrument used to acquire the data.
Select either image or cube.
Calibration level of the data (0=raw data .. 3=processed science-ready data)
A name of an observation target.
Media type (like image/fits) or similar of the data product searched
