PySIMBAD.py

Warning

This has been deprecated for a long time, even though it still works.

It was originally written as simbot, later renamed to PySIMBAD, in 2006 for the TÜBİTAK National Observatory (TÜBİTAK Ulusal Gözlemevi - TUG) Data Archive, to resolve alternative names of astronomical objects, i.e. name resolution. Now there are various tools for that.

It would be wise to use this only for educational purposes, and use astroquery for production. https://github.com/astropy/astroquery

About

This is a simple script, written in a simple manner.
Just connects to the CDS-Simbad Astronomical Services and retrieves information parsing the HTML files.
Can be used both as a Python module, or a standalone program.
Still has a lot to do, I'll add some stuff when I have the time.

Dependency

Python 2.6.x

Usage

Can be used as a standalone program. PySIMBAD.py <object name> This will output everything that can be retrieved about the object.

Example :

PySIMBAD.py "bl cam"

Also can be used as a Python module.

Let's first import it.

import PySIMBAD as sim

Now we build a link for our desired object name, and we assign it to an object name (here named as "star"),

link = sim.buildLink("sirius")

star = sim.simbad(link)

Now let's see what we can do with it,

dir(star)

['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'dec', 'fk4', 'fk5', 'flux', 'flux_num', 'gal', 'getCoord', 'icrs', 'mainType', 'names', 'names_num', 'objectTypes', 'page', 'ra', 'refs']

So we have an attribute named fk5. Let's see what it does!

print star.fk5()

06 45 08.917 -16 42 58.02

print star.ra.__doc__

Returns a string RA joined by ':'

print star.ra(star.fk5())

06:45:08.917

Or we can just select the main type of the object (whether it's a galaxy, an asteroid, a supernova etc.)

print star.mainType()

Spectroscopic binary

How about the flux information?

print star.flux.__doc__

`Returns a dictionary of Fluxes according to their Colors.

Example :
>>> S.flux()
{'H': '-1.391', 'J': '-1.391', 'B': '-1.46', 'K': '-1.390', 'V': '-1.47'}
>>> S.flux()['J']
'-1.391'`

star.flux() {'H': '-1.391', 'J': '-1.391', 'B': '-1.46', 'K': '-1.390', 'V': '-1.47'}

Well, here's the best part (and it's why I started building it in the first place)

for i in star.names(): print i
