CALSPEC: WFC3 infrared grism spectrophotometry (Bohlin+, 2019)

The publicly available WFC3 IR grism observations of CALSPEC stars in the nominal stare mode include the white dwarf standard stars G191B2B, GD153, and GD71, plus 16 other CALSPEC stars. These spectra were acquired at multiple locations on the IR detector. Grism scanned mode observations of CALSPEC stars will be discussed in a subsequent publication (S. Deustua & R. Bohlin 2019, in preparation). All the separate G102 and G141 observations of a source are co-added and merged. The default merge point where the co-add switches from G102 to G141 is at 11250 {AA}. The fluxes of the two independent measurements agree within the accuracy goal of 1% at the merge point.
