VLASS Epoch 1 Catalogs

<strong>PyBDSF and SExtractor detection catalogs for the VLA Sky Survey (VLASS)</strong> Stroh, M. C., Terreran, G., Coppejans, D., Bright, J. and Margutti, R. All authors currently at:<br> Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA), 1800 Sherman Ave, 8th Floor, Evanston, IL 60201, USA<br> Department of Physics and Astronomy, Northwestern University, 2145 Sheridan Road, Evanston, IL 60208, USA Corresponding author:<br> Stroh, M. C. - [e-mail] <br> General notes about the files:<br> These files were created using the epochs 1.1 and 1.2 quicklook files for the VLA Sky Survey (VLASS, Lacy et al. 2020). Original files are saved in a csv format, and have been subsequently compressed. The columns from each file are defined from PyBDSF (Mohan &amp; Rafferty 2015) or Source Extractor (SExtractor, Bertin &amp; Arnouts 1996) output with the file name appended to each row. Files are ordered by VLASS file name, then by the detection ID defined by PyBDSF or SExtractor. Included files:<br> 1) vlass_epoch1_pybdsf_gaussian.csv.gz Contains gaussian fits to detections in the VLASS epoch 1 Quick Look images using PyBDSF. These gaussians may be combined into sources in vlass_epoch1_pybdsf_source.csv.gz. 2) vlass_epoch1_pybdsf_source.csv.gz Contains final source lists from PyBDSF from the VLASS epoch 1 Quick Look images after gaussians have been combined. 3) vlass_epoch1_sextractor.csv.gz Contains detections from SExtractor in the VLASS epoch 1 Quick Look images. Please refer to Stroh et al. (2021) for information on how PyBDSF and SExtractor were run to create these files.<br> For more information about specific columns, please refer to Mohan &amp; Rafferty (2015) or Bertin &amp; Arnouts (1996).
