VLA Sky Survey Quick Look ImagesQuick Look image products are 1x1 degree images of the 2-4GHz Stokes I continuum, and an associated image of the RMS. Images are grouped by tiles, as described at Tile Definitions and Observing Status, and individual images are are named as follows:
These directories contain the Quick Look images for the Pilot, VLASS1.1 and VLASS1.2 observing campaigns. In addition, the Test directory contains QA rejected images and miscellaneous tests, and the old_image_versions directory contains deprecated versions of the images. The Quick Look images were made using a simplified imaging algorithm that does not correct for wide-field effects, resulting in significant positional and flux density errors, as well as poor image quality compared to a typical pointed observation with the VLA. Before using these images for scientific purposes, the Users' Guide to Quick Look images should be consulted. |
