    Hi All,
    Please, find a forwarded message I got from Ramiro.
    Ramiro submitted the message to the list but it returned back.
    Regards
    Pawel.

    Hi, Good to see things improving in the momentum discrepancies. The fits you made to the points I sent have the same problem that convinced me to go back and measure the excitation curves of all magnets; they have intercepts that are not what happens in reality, specially D4 would have 128 gauss of permanent field. I sent the values corresponding to the fields we used during the run so that you can continue with the analysis of the 2001 data. According to Flemming, Kris H. is working on a database interface that will have the new information. The main benefit from that interface will come from the fact that with the permanent Hall probe readout (that is now correlated with the field value in the middle of the gap) we will have a reading of the actual field every 1.5 minutes. This is the information we want to include permanently in the software. I submitted this message to the dev list before lunch, but it was bounced back. I should have submitted from sgs1. Anyway I will talk to Kris H. about the database work. Ramiro
