About HSTaXe
HSTaXe is a Python package to extract spectra from all slitless spectroscopy modes provided by the Hubble Space Telescope Wide Field Camera 3 (WFC3) and the Advanced Camera for Surveys (ACS). It replaces aXe. HSTaXe has the same functionalities as aXe but, unlike aXe, does not require IRAF/PyRAF which is no longer supported by STScI.
