Sharing some Data for the following image:

The binary system located in NGC 1333, was observed using the James Webb Space Telescope (JWST) through the Near Infrared Imager and Slitless Spectrograph (NIRISS) Wide Field Slitless Spectroscopy (WFSS) mode. The key data shown include:

Spectral Data (top graph):

  • The spectrum of an object in the system is plotted with relative flux versus wavelength. The blue line represents data from the JWST NIRISS, while the red line shows the best-fit template (M8 spectral type with an extinction value ( A_V = 3.0 )).
  • The object is classified as a late M-type star (or brown dwarf) based on spectral fitting.

Images of the Binary System (middle row):

  • Two images using the F150W and F200W filters, show two closely spaced objects, possibly members of the binary system.
  • These images are in the infrared range and reveal the physical structure of the system.

Calibrated Slope Image Cutouts (bottom left):

  • These represent cutout images showing how the intensity changes as a function of wavelength in the F150W and F200W filters.
  • This likely provides more insights into the object's spectral features and how light is distributed across the system.

Template Model Fitting Map (right):

  • This map shows a model-fitting grid of spectral types (y-axis) against visual extinction values ( A_V ) (x-axis), with colored boxes highlighting the best-fit regions. The data suggest the candidate object fits in the M-type spectral category with an extinction value around 3-4 magnitudes.

For further details, the data in Appendix B, Figure 14 provides more comprehensive insights, and additional context can be found in Section 5.2 of the original document.
