Dimensions of coeff in alignment.py
In alignment.py, line 234, there is an error raised because the numpy array coeffs is only one dimension.
vertex_x = -coeffs[1, :] / (2 * coeffs[2, :])
should be simply coeffs[1] and coeffs[2], depending if f_vals.shape is 1 or 2.
Note that this problem can be solved if the f_vals input values has a 2nd raw of values even for a simple 1D fit.
