| def getChebOrder | ( | self, | |
lev_i = -1, |
|||
lev_j = -1 |
|||
| ) |
Return order of Chebyshev polynomial fitting the collision strengths of selected transition.
If transition not specified, return result for all transitions.
Usage:
O3.getChebOrder(4, 2)
Parameters:
- lev_i upper level (default= -1, returns complete array)
- lev_j lower level (default= -1, returns complete array)
| def getOmega | ( | self, | |
| tem, | |||
lev_i = -1, |
|||
lev_j = -1 |
|||
| ) |
Return interpolated value of the collision strength value at the given temperature
for the complete array or a specified transition.
Usage:
O3.getOmega(15000.)
O3.getOmega([8e3, 1e4, 1.2e4])
O3.getOmega([8e3, 1e4, 1.2e4], 5, 4)
Parameters:
- tem electronic temperature in K. May be an array.
- lev_i upper level
- lev_j lower level
| def getOmegaArray | ( | self, | |
lev_i = -1, |
|||
lev_j = -1 |
|||
| ) |
Return array of original tabulated collision strengths for a given transition,
as a function of temperature.
Usage:
O3.getOmegaArray()
Parameters:
- lev_j lower level (default= -1, returns complete array)
- lev_i upper level (default= -1, returns complete array)
| def getSources | ( | self | ) |
Return bibliographic sources for atomic data, as listed in the headers of the fits files.
| def getTemArray | ( | self, | |
keep_unit = True |
|||
| ) |
Return array of tabulated original temperature points (as in fits file)
of collision strengths.
Parameters:
- keep_unit return temperature in file units (default) or change it to Kelvin (False)
| def initOmegas | ( | self, | |
OmegaInterp = 'Cheb' |
|||
| ) |
Initialization of the Chebishev orders and coefficients. This method is called by __init__ and when
OmegaInterp is changed.
Parameter:
- OmegaInterp one of ('Cheb', 'Linear')
