Data processing for Coma Legacy IFU Survey

clifsPy

This is a data analysis and processing package for the Coma Legacy IFU Survey. This package permits the combination and processing of Level 1 data cubes from the WEAVE spectrograph.

The standard pipeline run includes the following analysis steps:

Cube pre-processing and combination

• Apply flux calibration
• Spectral and spatial binning (optional)
• Background subtraction (optional)
• Combine blue and red level 1 cubes
• Fix WCS (optional)

Multi-wavelength

• Make multi-wavelength cutout images from available ancillary data
• Currently supported: GALEX, DESI Legacy, CFHT, Herschel, LOFAR
• Make integrated CO spectrum (optional, IRAM or ALMA)

MaNGA Data Analysis Pipeline

This module makes use of the MaNGA data analysis pipeline (Westfall et al. 2019)

• Push the calibrated WEAVE data cubes through the MaNGA data analysis pipeline (DAP)
• Custom class in order to format the WEAVE data suitably for entry into the MaNGA DAP
• DAP performs full spectral fitting, outputs maps of: stellar kinematics, emission line flux, gas kinematics, absorption line indices, etc.

Products

• Creates value-added products outside of what is produced by the MaNGA DAP
• Currently includes star formation rate and stellar mass maps
• More to be added...

Plotting

• Creates diagnostic plots to evaluate the performance of the MaNGA DAP run

Usage

The package is centered around the clifsipe command, which takes a CLIFS ID value as input. All of the standard pipeline steps can be run as:

clifspipe $clifs_id --default_run

It can also be used in a modular fashion, for example to only run the initial data cube processing:

clifspipe $clifs_id --process_cube

Or to just run the MaNGA DAP and make the diagnostic plots:

clifspipe $clifs_id --manga_dap --make_plots

The pipeline expects to find two configuration files in a config_files directory. One, clifs_{$clifs_id}.toml that sets various options and file paths for the pipeline run, and a second configuration file for the MaNGA DAP, the filename of which is set in the CLIFS ID configuration file. Examples of both files can be found in examples/
