PyOngc

A python interface for accessing OpenNGC database data

https://travis-ci.org/mattiaverga/PyOngc.svg?branch=master https://coveralls.io/repos/github/mattiaverga/PyOngc/badge.svg?branch=master https://ci.appveyor.com/api/projects/status/ee72q5vkbi7quri6/branch/master?svg=true

Description

PyOngc provides a python module to access astronomical data about NGC and IC objects.

The data is based on OpenNGC database https://github.com/mattiaverga/OpenNGC.

It is composed by a python module and a command line interface named (guess what) ongc, which can be used to quickly see object details or build object lists based on several parameters.

PyOngc can pass data to PyEphem in a simple way to get ephemerides of NGC/IC objects: see the documentation about ongc.xephemFormat method.

Usage

>>> from pyongc import ongc
>>> DSOobject = ongc.Dso("NGC7000")
>>> DSOobject.getCoords()
array([[20.  , 59.  , 17.14],
       [44.  , 31.  , 43.6 ]])

Object data is easily available from command line also:

$ ongc view NGC7000 --details
