Data Access

  • Flux-calibrated IRTF/SpeX spectra in Zhang 2021bc
    - 55 late-T dwarfs: 57 spectra in total as two objects in our sample each has spectra taken with two spectral resolutions
    - Column 1: wavelength (unit: um)
    - Column 2: flux (unit: erg/s/cm2/A)
    - Column 3: flux uncertainty (unit: erg/s/cm2/A)
