tianqin_psd
- legwork.psd.tianqin_psd(f, L=<Quantity 173205.08075689 km>, t_obs=<Quantity 5. yr>, approximate_R=None, confusion_noise='huang20')[source]
Calculates the effective TianQin power spectral density sensitivity curve
Using Eq. 13 from Huang+20, calculate the effective TianQin PSD for the sensitivity curve
Note that this function includes an extra factor of 10/3 compared Eq. 13 in Huang+20, since Huang+20 absorbs the factor into the waveform but we instead follow the same convention as Robson+19 for consistency and include it in this ‘effective’ PSD function instead.
- Parameters
- ffloat/array
Frequencies at which to evaluate the sensitivity curve
- Lfloat
Arm length
- t_obsfloat
Observation time (default 5 years)
- approximate_Rboolean
Ignored for this function
- confusion_noisevarious
Galactic confusion noise. Acceptable inputs are one of the values listed in
legwork.psd.get_confusion_noise()or a custom function that gives the confusion noise at each frequency for a given mission length where it would be called by running noise(f, t_obs) and return a value with units of inverse Hertz
- Returns
- psdfloat/array
Effective power strain spectral density
