Preview of interactive plot demonstrating the position of COSTCO-I members in the volume of CLAMATO. The red, yellow, and cyan surfaces represent Wiener-filtered Lyα flux of CLAMATO smoothed with a 4 h ⁻¹ Mpc Gaussian filter, ﹩{\delta }_{F}^{{\rm{w}}}=-0.1,0,0.1﹩, respectively; the white dots are the positions of galaxies in the catalog by Momose et al. (2022). We emphasize the core members of COSTCO-I with red spheres, and it is clear that there is no Lyα excess (red contours) associated with the protocluster. The static preview shows the field in the transverse plane projected over the redshift range 2.27 < z < 2.33, but the online version is fully 3D with a redshift range of 2.18 < z < 2.41. In the interactive figure, users can zoom in/out and/or rotate the figure about any axis. At the bottom of the interactive figure are four buttons. These allow the user to reset the view back to the default orientation, a view along R.A., a view along decl., and a view along redshift.

An interactive version of this figure is available in the online journal.
