The
ASKAP
Update for February reports on the status of CASDA (the CSIRO
ASKAP Science Data Archive), the resumption of survey operations, the
next RACS (Rapid ASKAP Continuum Survey) epoch, and plans for ongoing
development.
Recent updates to the ASKAPsoft continuum imager allow simultaneous
imaging in several directions. In future this could be used for
direction-dependent calibration, but our first goal is to implement a
system that can remove ("peel") bright sources from outside a field of
interest to prevent their PSF from contaminating the main image. This
will work alongside a first iteration of the RACS-based sky model,
which the processing pipeline can access to determine the location of
bright sources.
The image above shows ASKAP antennas stowed in readiness for
an approaching storm, which darkened the background skies.
