Wavelength and Flux calibration of the ACS/SBC PR110L and PR130L prisms

Wavelengthand flux calibrations are presented for the ACS/SBC PR110L and PR130L slitless spectroscopy modes. The calibrations were derived from Cycle 13 observations of two QSOs at redshift z=0.098 and z=0.168 (for the wavelength calibration) and two white dwarf standards (for the flux calibration), and are made available to users as configuration files for the aXe software package. Both the traceand wavelength solutions include spatial variations across the SBC detector, and flat-fields (compatible with the aXe flatfield cube format) are provided to correct for the detected large-scale sensitivity variations. Shifts between direct images obtained in different passbands are also quantified, and corrections relative to the reference (F165LP) passband are given.
