Function Documentation

def pyneb.utils.manage_atomic_data.atom2chianti

(

atom

)

def pyneb.utils.manage_atomic_data.extract_flt

(

str_

)

Return the first float in str_, removing the no digit (and no dot) leading part of it.
Ex:
extract_flt('123.00?') -> 123.00

def pyneb.utils.manage_atomic_data.getLevelsNIST	(		atom,
			NLevels = None
	)

Return a numpy.array containing the NIST data related to the levels for the given atom
The keys of the recarry are: conf, term, J, energy, ref
Example:
    data = getLevelsNIST('O3')
    energies = data['energy']

def pyneb.utils.manage_atomic_data.getNIST	(		elem,
			ion,
			fileout = None
	)

This will download the enegy levels from NIST and write them to a file
example: getNIST('O',3) write the o_iii_levels.dat file

def pyneb.utils.manage_atomic_data.print_stout_coll	(		Atom,
			file_
	)

def pyneb.utils.manage_atomic_data.readNIST	(		NISTfile,
			NLevels = None
	)

The NIST levels file must be obtained from this page:
    http://physics.nist.gov/PhysRefData/ASD/levels_form.html
with the following options:
    Level Units: cm-1
    Format output: ASCIIda
    Display output: in its entirely
    Energy ordered
    Level Information: Principal configuration, Principal term, Level, J
