I have updated the following frontend models to implement the time-domain DCPD cross correlation technique.

• omc.mdl (master model)
• h1omc.mdl
• CAL_CS_MASTER.mdl
• h1calcs.mdl

The h1omc and h1calcs models will be installed and restarted tomorrow during the maintenance period.

[The changes]

Here is a list of things that I newly added today in the OMC models (namely h1omc.mdl and omc.mdl). Also the attached are screenshots of relevant part of the models.

• I connected the DCPD null signal to the readout box in which the normalization takes place.
• In the readout block, a virtually identical normalization to the sum signal was added for the null signal.
• An IPC sender was added in order to send the null signal to h1calcs.

Here is a list of things I added today in the CAL CS models, e.g. h1calcs.mdl and CAL_CS_MASTER.mdl.

• Added an IPC receiver.
• Added two 16 kHz frame channels (called H(L)1:CAL-DELTAL_A and H(L)1:CAL_DELTAL_B).
• Added two filters, one summation and subtraction operations to produce the A and B channels.

After these changes, I confirmed that they compile without an error. They are ready for tomorrow's installation. The models are checked into svn.
