| ASKAP Pilot Survey Data in CASDA |
|
The ASKAP Update
for May is now available, and includes news on the release of
Pilot Survey data into CASDA (the CSIRO ASKAP Science Data Archive).
The public release of data from WALLABY’s observations of the Hydra
cluster marks the first release of full-volume spectral line pilot
data. Although some artefacts remain in the
continuum-subtracted data cubes and further processing improvements
will be made, a large section of the Hydra field has been successfully
analysed by the WALLABY team using the spectral line source finding
software SoFiA. The Hydra observations
detected roughly 150 galaxies in a region where only 8 were previously
known!
Images from the VAST continuum pilot survey are also starting to appear in CASDA. The image above shows the sky coverage and an example image from the VAST pilot survey data. VAST uses short, 12-minute observations to survey large areas, looking for sources that have changed. (Image credit: Emil Lenc) |
