== Task list ==
{{{#!wiki green/solid
Note: some of the tasks can be done in parallel.
}}}
 * Make the clean booth clean and useful; prepare tables, shelves, ethanol, tools...
 * Open the side flanges and top lid; attach white tapes (SPV-202) to the open flanges to protect them.
 * Check the positions and rigidity of the inner tower, and the dirtiness.
 * Check also fixing method for the inner tower; at least in IXAm it seems re-working is needed.
 * Measure several heights and widths
 * Make grooves to be references so that we can locate the NAB properly with respect to the interferometer's main beam.

 * Replace Wire-Holder for NAB
 * Take OpLev measurements -> place the PSD and Data-Analyzer
