In the directory /work/halla/ndelta-2/databases are the following files.

1. The database optimizing beta, scint adc and vdc for runs
    1025 to 1765 is db_ndelta_1765_vdc_opt .
   This database also has the correct coefficients for the BPM
	determined by Zhengwei Chai

2. The database db_835_e_emily has electron arm delta 
    optimized by Emilie Penel for Dec 1999 12C elastic data.

3. The database db_ndelta_3.5  has electron theta,phi and ytgt
	and y000,t000, and p000 optimized by Nilanga.
   He started with the VCS 3.5 GeV database
   Optimized the t000,y000 and p000 using run 1760
   Then optimize the theta and phi using 1H data and sieve
     using a reduced number of elements in theta.
   The optimized the Y030 element . 
   For now the delta matrix is used unchanged.
   There are no T000 nor Y000 terms for electron optics in this database.

4. The database db_840_dp_h_rikki has hadron arm delta
    optimized by Rikki Roche for Dec 1999 12C elastic data.

5. The database db3500_e_zwchai is an improved
	version of db_ndelta_3.5 for electron arm optics.

6. The database db845_e_zwchai has the electron arm
	theta,phi and ytgt optimized using the Dec 1999 845 data.

7.  The database db845_h_zwchai has the hadron arm
	theta,phi and ytgt optimized using the Dec 1999 845 data.

8. The database  db700_1400_h_zwchai has the hadron arm
	the ytgt and y000,p000,t000 optimized using
	700MeV, 1.0GeV 1.3GeV ndelta pointing data 
	

9. The database db_ndelta_period1 has
    a) the beta,scint adc and vdc from db_ndelta_1765_vdc_opt
    b) the bpm coefficients from db_ndelta_1765_vdc_opt
    c)  electron delta,theta,phi and y plus y000,t000,p000 from
          db3500_e_zwchai
    d) hadron delta from db_840_dp_h_rikki
    e) hadron phi,theta from db845_h_zwchai
    f) hadron ytgt and y000,t000,p000 from db700_1400_h_zwchai

10. Main question is the gamma for each spectrometer. Nilanga will
    determine the gamma. The energy for arc is stable but
    still awaiting final numbers for e-p.
