5σ point source detection limits of SPHEREx surveys and 7DS. The colored squares show the depths of the three layers of 7DS, with the RIS at the top, followed by the WTS and IMS layers. The circular markers show the depths of SPHEREx full-sky and deep surveys from the top. The blue, red, green, and pale blue triangles denote the 5σ point source depths of other popular optical and NIR imaging surveys (SDSS York et al. 2000, unWISE Schlafly et al. 2019, VHS McMahon et al. 2013, and Pan-STARRS Chambers et al. 2016). The shaded regions show the wavelength ranges of the plotted broadband filters as labeled at the top: u, g, r, i, z, Y, J, H, K_s, W1, and W2.
