NGSF - the Next Generation SuperFit in Python - is a template matching tool for the spectral
classification of Supernovae of all major types accompanied by a host galaxy,
inspired by Andy Howell's IDL Superfit (2005ApJ...634.1190H). The software uses chi squared
minimization to find the best combination of host galaxy and supernova templates
from a library of spectra in order to match a spectrum of an object of interest.
NGSF can be obtained as a standalone package from GitHub, here. The bank of
spectral templates should then be downloaded from WISeREP, here, and be placed
in the base folder.
Besides the option to use NGSF locally, on your computer, it is now also
available for online execution on WISeREP for any given spectrum that already
exists on the repository, without having to download the spectrum or the standalone
package. This is done via the iF button of a spectrum entry on the Spectra Search Page.
Note that you must be logged into WISeREP in order to make use of this tool. If
you don't have an account, please register here.
For further details, please refer to the documentation on the GitHub,
and to the help page on WISeREP for more detailed instructions on how to execute
NGSF directly on WISeREP.
If making use of this tool in your research, please make sure to cite Howell et
al. 2005 (2005ApJ...634.1190H) as the source of the original code, and this
AstroNote - 2022TNSAN.191....1G - as the source for the new implementation.
