-
Zap now requires Python 3.5 or later, and Astropy 2.0 or later.
-
Compatibility with the NFM-AO mode.
-
Ignore the notch filter region in the 'median' and 'fit' methods for the
continuum filter (cftype). -
Change the default continuum filter method (
cftype) to 'median' and
remove the 'weight' method. The previous default method ('weight') has some
problems with the treatment of spectra edges and with the notch filter edges
for the AO modes, and is also introducing bumps in the red wavelengths. -
Add a command-line argument for
nevals. -
Scipy 0.18.1 or later is required, because of SVD convergence issue with
previous versions. -
Add a function to mask the cube edges (
zap.mask_nan_edges): the spaxels
at the edges of the cube may have a lot of NaNs in their spectra, so ZAP
does not subtract the sky on these which leaves high residuals.
