ssdc-sedbuilder 1.1.2

A client to the ASI-SSDC's SED Builder API.

sedbuilder

The sedbuilder package implements a Python interface to the ASI Space Science Data Center's SED Builder REST API.

Overview

This package provides programmatic access to multi-wavelength spectral energy distribution (SED) data from catalogs, surveys, and archival observations across the electromagnetic spectrum. It is based on SED Builder, a software developed at the ASI-SSDC to produce and display the SED data over the web.

Installation

pip install ssdc-sedbuilder

Quick Start

You can fetch data querying a source name or its coordinates.

from sedbuilder import get_data

# By coordinates
response = get_data(ra=244.9795, dec=-15.64022)
# By name
response = get_data(name="Sco X-1")

# Access data in different formats
table = response.to_astropy()     # Astropy Table
data_dict = response.to_dict()    # Python dictionary
jt = response.to_jetset(z=0.034)  # Jetset table
json_str = response.to_json()     # JSON string
df = response.to_pandas()         # Pandas DataFrame (requires pandas)

# Gets references to the dataset catalog and papers
refs = response.sources()

When calling get_data by name, resolve_name queries the SSDC server — which checks SSDC, SIMBAD, and NED — falling back to the CDS Sesame resolver via astropy if no match is found.

from sedbuilder import resolve_name

(ra, dec), db = resolve_name("Crab Nebula")

Resolving a source name takes time. We suggest querying on coordinates when available.
