"Filaments in and between galaxy clusters at low and mid-frequency with the SKA telescope" (Figures 6 to 13, B.1 and B.2)
<p>This file contains Figures 6 to 13, B.1 and B.2, from the paper "Filaments in and between galaxy clusters at low and mid-frequency with the SKA telescope", Vacca et al., accepted for publication on A&A on 25 September 2024.</p>
The data and codes corresponding to "Calibration of an SKA-Low prototype station using holographic techniques"
<p>The data and codes for our paper "Calibration of an SKA-Low prototype station using holographic techniques" being submitted to Radio Science. The data were acquired on 30-11-2022 around noon. The contents of this dataset are as follows.</p> <ol> <li>channel_cont_20221130_17259_0.hdf5 - voltage dump file with the AAVS2 antenna voltages.</li> <li>chan_204_20221130T04473900.uvfits - channelised and correlated uvfits file for the AAVS2 voltage dump. This can be imported into conventional radio astronomy packages such as miriad.</li> <li>miriad_mfcal4holo.sh - script to process the uvfits file in miriad.</li> <li>chan_204_20221130T04473900.uv_aver_phc.zip - final calibrated miriad data as a zip file.</li> <li>antenna_locations_aavs2.txt contains the AAVS2 antenna locations in metres.</li> <li>channel_4_1_1669783636.945334.dada - beamformed voltage stream from EDA2 with the beam towards the Sun.</li> <li>Holography_combined.ipynb - jupyter notebook to perform all the holographic techniques with the data given above and generate all the figures used in the paper.</li> </ol>
Material for the blog post "Building phylogenetic trees with SKA"
