WFC3/UVIS G280 Calibration and Reference Files

The configuration and calibration files presented on this page are in the correct format to be used with the HSTaXe extraction software. To use these calibration products with HSTaXe, copy them into a directory and set your AXE_CONFIG_PATH environment variable to point to that directory.  The configuration files (v.2.5) with wavelength and trace calibration information were created using in-flight calibration data with details given in WFC3 ISR 2017-20. The sensitivity files were generated by the calibration presented in WFC3 ISR 2020-09. The older versions of the reference files, also provided here, were created using ground calibration data (WFC3 ISR 2009-01).
