Including data to atomic resolution

After the model has undergone a first round of corrections, the high-resolution data can be included. The stir instruction is used to gradually introduce the new data 

Use data between 10 A and full resolution Begin refinement with data to 1.5 A, then with every cycle include successive 0.1 A shells of data 

If the data extend to more than atomic resolution (e.g. dmin 0.9 A), it may he more efficient to do some work on the model including only data to some intermediate
