Description
MeerKAT Large Area Synoptic Survey (MeerKLASS) has observed 236 square degrees of sky at the L band (900-1670 MHz) at declinations < -25 degrees. We present radio continuum images and a catalog of radio sources detected at a signal-to-noise ratio (S/N) > 5 across multiple sub-bands. The data used for this study were collected using the “on-the-fly” interferometric imaging scanning mode, where the MeerKAT array moves back and forth around a fixed point while saving observations every 2 seconds. This method allows for efficient mapping of large sky areas over a few hours, with the observation point gradually shifting as the Earth rotates. The resulting catalog has a median spatial resolution of 10 arcsec. The flux density scale ratio and astrometric accuracy, derived from comparison with previous catalogs, exhibit a scatter within 10% and 1 arcsec, respectively. We also present the spectral indices of the detected sources, providing insights into the source populations and their distribution.
