    3. 271544; 6.5 degree delta, Zd = 43deg;
    4. 271678; 7.4 degree delta, ZD = 41deg;
    5. 271684; 7.8 degree delta, ZD = 42deg;
    6. 271685; 6.3 degree delta, ZD = 41deg;
    7. 271691; 8.0 degree delta, ZD = 44deg;
    8. 271694; 7.4 degree delta, ZD = 44deg;

Notes for Data Management

  1. Be aware of new objects “nightly defocus” an.d “nightly refocus” after p.m. standards “nightly defocus” and “nightly refocus” after p.m. standards
  2. Do not process the following exposures:
