class mcfacts.vis.LISA.LISA(Tobs=126232599.0528, Larm=2500000000.0, NC=2, transfer_file='R.txt')

Bases: object

LISA class

Handles LISA’s orbit and detector noise quantities

LoadTranfer - read in, and store, transfer function data file

SC_Orbit    - return calculate spacecraft (S/C) positions

SC_Seps     - return unit-separation vectors between LISA S/C

Pn          - return LISA's strain power spectral density

Pn_WC       - return LISA's strain power spectral density with confusion noise estimate

SnC         - return confusion noise estimate

Sn          - return LISA's sensitivity curve

Tobs - LISA observation period (4 years is nominal mission lifetime) Larm = 2.5e9 LISA’s arm length, current design arm length,

constant to 1st order in eccentricity

NC - Number of data channels

__init__(Tobs=126232599.0528, Larm=2500000000.0, NC=2, transfer_file='R.txt')

Tobs - LISA observation period (4 years is nominal mission lifetime) Larm = 2.5e9 LISA’s arm length, current design arm length,
