Galaxy Data Definitions

Define allowed quantities for FRB galaxies.

Uncertainty is valid for any quantity with _err add-on (e.g. W1_err). Also supports _loerr and _uperr suffixes.

Overview

This module defines constants, valid field names, and data structures used throughout the FRB galaxies package. It serves as a central registry for allowed values in galaxy data dictionaries and provides validation lists for data integrity.

Data Validation

The definitions in this module are used throughout the package for:

Input Validation

  • Checking that dictionary keys correspond to recognized fields

  • Ensuring consistent naming conventions across modules

  • Preventing typos in field names

Data Integrity

  • Validating measurements against expected ranges

  • Cross-checking reference formats

  • Maintaining compatibility with external databases

Documentation

  • Providing complete lists of supported measurements

  • Defining units and conventions for each quantity

  • Enabling automatic documentation generation

Usage Examples

Validation in FRBGalaxy objects:

from frb.galaxies import defs
from frb.galaxies.frbgalaxy import FRBGalaxy

# Create galaxy object
galaxy = FRBGalaxy(ra=180.0, dec=45.0, frb=frb_object)

# Add photometry - keys must be in valid_photom
galaxy.photom['DES_g'] = 22.5
galaxy.photom['DES_r'] = 21.8
galaxy.photom['DES_i'] = 21.3

# Validate photometry dictionary
valid_keys = set(galaxy.photom.keys()).issubset(set(defs.valid_photom))
print(f"All photometry keys valid: {valid_keys}")

Checking available measurements:

# See what emission lines are supported
print("Supported emission lines:")
for line in defs.valid_neb_lines[:10]:  # First 10
    print(f"  {line}")

# Check derived property options
print("\\nPhysical properties from SED fitting:")
for prop in defs.valid_derived_photom[:8]:
    print(f"  {prop}")

Working with survey bands:

# Build photometry for specific survey
des_filters = ['DES_' + band for band in defs.DES_bands]
print(f"DES filters: {des_filters}")

# Check if galaxy has complete DES photometry
has_des = all(filt in galaxy.photom for filt in des_filters)
