This function calculates the stress as measured by a LIGO like detector due to a hung-up collapsing core. It uses the routines

The arguments are:

`h[]`: Output. An array which holds the detector stress due the gravitational wave of the hung-up core at equally spaced time intervals.`h[]`must be allocated sufficient memory before being passed to`LS_waveform()`.`phys_const`: Input. A structure of type`LS_physical_constants`(see subsection ) which contains the physical parameters of the hung-up core.`sky_theta`: Input. The polar angle from zenith in radians.`sky_phi`: Input. The azimuthal angle (measured counter clockwise from first arm) in radians.`polarization`: Input. The polarization angle in radians.`dt`: Input. The time interval (in seconds) at which the detector stress values should be output.`n_samples`: Input. The number of detector stress values to be output (i.e. the number of elements in the array`h[]`).

- Comments: This function currently calculates the stress at a user
defined distance from the hung-up core. For realistic distances, this leads
to small values (of the order of 10e-22 at 10 MPc). If one wishes to have
numbers of the order of unity, simply set the distance in the structure
`phys_const`to be 10e-22.
