Caption: Figure 6.

NIRCam grism spectrum of HDF850.1 obtained from FRESCO. Top left: same Hα emission-line map as in Figure 2, but rotated to align with the dispersion direction. Top right: 2D grism spectrum of HDF850.1. Hα line emissions from the northern and southern components are indicated with solid vertical red lines, and expected [N II] λ6583 line emissions are indicated by dashed lines. The relative positions of Hα emission from HDF850.1-N and S are different from those in the top left panel, suggesting different velocities of the two components. Bottom: 1D spectrum of HDF850.1 obtained by collapsing the 2D spectrum within ±0.″5 spatial offset. The uncertainty spectrum is shown as the filled gray region. The full 1D spectrum is displayed in Appendix, Figure A3.
