pylops.utils.seismicevents.makeaxis(par)[source]¶

Create axes t, x, and y axes

Create space and time axes from dictionary containing initial values \((ot, ox, oy)\), sampling steps \((dt, dx, dy)\) and number of elements \((nt, nx, ny)\) for each axis

Parameters:	par : `dict` Dictionary containing initial values, sampling steps, and number of elements
Returns:	t : `numpy.ndarray` time axis t2 : `numpy.ndarray` double time axis (symmetric to zero) x : `numpy.ndarray` x axis y : `numpy.ndarray` y axis (`None`, if \(oy, dy, ny\) are not provided)

Examples

>>> par = {'ox':0, 'dx':2, 'nx':60,
>>>        'oy':0, 'dy':2, 'ny':100,
>>>        'ot':0, 'dt':4, 'nt':400}
>>> # Create axis
>>> t, t2, x, y = makeaxis(par)
