I$_{2}$ Cell and Light Monitor

There is no significant difference between the preparation for observation with and without the I$_{2}$ cell and the light monitor. Note that the throughput of the I$_{2}$ cell is about 85%. One must carefully prepare the sequence of observations when the I$_{2}$ cell and the light monitor are used. Two standard spectrograph setups are available: StdI2a and StdI2b.
