Astro Source

Tools for managing source information and associated data.

Dependencies:

• Commonly used packages: astropy, numpy
• toolkit, configparseradv

How it works?

A source is defined by a configuration file of the form:

[INFO]
name: my_source
distance: 1 kpc
ra: 1h00m00s
dec: 1d00m00s
frame: icrs
luminosity: 1 L_sun

The values associated to ra, dec, distance and luminosity can be accesed directly as attributes. These will return an astropy Quantity representation of the stored values. Additional stored properties can also be read as Quantity with the get_quantity method. The position of the source can also be retrieved as an astropy.coordinates.SkyCoord object through the attribute position.

Addtional sections can be used to specify data associated to that source or subsources:

[MM1]
type: subsource
name: mm1
ra: 1h00m01s
dec: 1d00m01s
radius: 0.1 arcsec

[data1]
type: fits_file
file: /path/to/file.fits

[data2]
type: spectral_cube
file: /path/to/file.fits

Subsource information can be retrieved by, e.g., source.subsources['MM1'].info['radius']. The data is loaded upon request (e.g. source.load_data(data1)) to save resources.
