Image Details
Caption: Figure 2.
Stokes I image of the Perseus molecular cloud obtained from the 19B VLA observations in D-configuration. This mosaic represents the total-intensity map produced using the multifrequency synthesis imaging technique with wide-field corrections and deconvolution applied via the tclean algorithm in CASA. The image covers the central region of the molecular cloud with a synthesized beam size of approximately 46″ and a pixel scale of 2﹩\mathop{.}\limits^{\unicode{x02033}}﹩5. The enhanced sensitivity achieved in this dataset (∼80 μJy beam−1) allows for the detection of numerous faint background radio sources, which are critical for probing the magnetic field structure via Faraday rotation.
