Description: An IDL code designed for estimating galaxy redshifts from spectroscopic data using wavelets.
Notes: Requires iSAP installation


The Darth Fader method is a catalog cleaning method for redshift estimation which is described in:

Code

The code will be soon integrated in the next version of the iSAP software. Meanwhile, it can be used following these instructions:

The documentation is available here.

Results

Benchmark data are available here, and the following routine shows how to use it on these benchmark data:

Running this routine, we obtain the following results:

  • % of catastrophic failures before cleaning = 22.09
  • % of galaxies retained after cleaning = 75.80
  • % of catastrophic failures after cleaning = 4.29
