- To use 3/6/2012 zero points and EE curves, copy "filters_2012.dat" to "filters.dat"
- To use UVIS zero points from WFC3 ISR 2017-14 (10 pixel aperture) and EE curves posted March 8, 2016 (adjusted to 10 pixel aperture), and IR zero points posted March 6, 2012 and EE curves interpolated from ir_ee_model_smov.dat, using pivot wavelengths, copy "filters_2017.dat" to "filters.dat"
- Distortion coefficients from v5r1512gi_idc.fits (UVIS), v5r1512fi_idc.fits (IR) are available as uvis_idctab_2011.dat and ir_idctab_2011.dat, but may need to be reformatted.
