The seven GMRT Band-4 pointings (labeled P1–P7) overlaid on the HST-ACS F814W image of the COSMOS field (in gray scale; A. M. Koekemoer et al. 2007; N. Scoville et al. 2007). The FWHM of the GMRT Band-4 primary beam at 650 MHz, 0﹩\mathop{.}\limits^{{\unicode{x000b0}}}﹩7, is indicated by the red circle around each pointing center. In each pointing, the colored points indicate the locations of star-forming galaxies (excluding active galactic nuclei) with M_* ≥ 10⁹ M_⊙ at z = 0.875−1.50 and with accurate redshifts Q_f = 4 (A. A. Khostovan et al. 2026) from the DESI, zCOSMOS-Bright, C3R2, and DEIMOS-10K surveys.
