Six binary system candidates identified in the NIRISS F150W and F200W images of NGC1333 with a separation of <1.″ Each pair is shown in the world coordinate system, with the F150W image on the left and the F200W image on the right. The color scales are normalized differently for each pair to clearly see the companion objects. Thus, the difference in brightness between the images for two pairs is not representative of their comparative flux. The primary objects for binaries NN7 and NN10 are saturated in the images. See Table 2 for measured coordinates and separations.
