WCU laser signal is too low

[oczoske]

What happened?

I've found two spots which might cause the laser lines to be too faint (as reported by A. Glasse):

• metis_wcu.py, l. 395: self.intens_lamp = self._laser_intensity() - this seems to lack the integrating-sphere multiplication factor (which is around 19).
• metis_wcu.py, l.448: flux = ((power_l * line_l(lam) + power_m * line_m(lam) + power_t * line_t(lam)) / (np.pi * self.d_is_in**2 / 4))
  This assumes that the power is distributed over the integrating-sphere entrance window (diameter d_is_in). In reality the lasers are coupled via fibres that are almost certainly much smaller than the window. The WCU team need to provide information how that works exactly, what the fibre diameter is, and also about the expected fibre losses.
