write_fits requires 2x memory because it makes a copy

Open msyriac opened this issue 7 years ago • 0 comments

Currently, write_fits makes a copy of the passed array because there is a concern that the FITS write routines could modify the input map. Is there some way to circumvent this without having to make a copy, other than switching to hdf5?
