资源简介：
WFC3IR-FLUXCAL is a collection of 19 spectral energy distributions (SEDs) using HST WFC3IR grism spectroscopy. Two IR grisms, G102 and G141, cover a wavelength range from 0.8-1.7 microns at a resolution of R=200 and R=150, respectively. These WFC3 SEDs overlap existing CALSPEC STIS flux distributions between 0.8-1.0 microns and agree within 1%. The SEDs for the 19 targets are provided in both FITS and ASCII text format. A table of sensitivities is also provided for both grisms. Extracted signals should be divided by these sensitivity values to obtain absolute fluxes after correcting for changes in sensitivity with time and count rate non-linearity (see Bohlin & Deustua 2019 for complete instructions on how to apply the corrections provided by this HLSP).
