    keyword=EPR Procedure for Tilghman at Transverse Mode

    When target is at transverse (270 degree) mode, should

    turn off transverse lasers;
    rotate field to 0 degree;
    turn on 3 longitudinal lasers (#5, #6 and #7);
    wait until temperature is stable (15 minutes);
    Perform EPR;
    turn off longitudinal lasers;
    Close epics control windows for longitudinal lasers and open windows for transverse lasers;
    rotate field to 270 degree;
    turn on three transverse lasers;

    continue taking data.

    Calibration constant for Tilghman with 1 laser (#6) is:
    Polarization(%) = 0.92690144 * freq shift (KHz)
