xabssys Documentation¶

This ipython Notebook is intended to provide documentation for the linetools GUI named XAbsSysGui.

Enjoy and feel free to suggest edits/additions, etc.

Before Launching the GUI¶

If you are a Mac user, we highly recommend that you set your matplotlib backend from MacOSX to TkAgg (or another option, see backends).

Launching the GUI¶

From the command line (recommended)¶

We recommend you use the script provided with linetools.

Then it is as simple as:

> lt_xabssys spec_file abssys_file

The abssys_file is expected to be a JSON file that contains an AbsSystem (likely written with the write_json method).

Here are the current command-line options:

> lt_xspec -h
usage: lt_xabssys [-h] [-outfile OUTFILE] [-llist LLIST] [--un_norm]
              spec_file abssys_file

Parse for XAbsSys

positional arguments:
  spec_file         Spectral file
  abssys_file       AbsSys file (JSON)

optional arguments:
  -h, --help        show this help message and exit
  -outfile OUTFILE  Output filename
  -llist LLIST      Name of LineList
  --un_norm         Spectrum is NOT normalized
