There is no need for special command in scalepack to process partial data set.
However, in such cases it may be very helpful to add:
scale restrain 0.02
b restrain 0.2
To restrain scale and b factors. If frames are quite narrow, there may be
not enough observations to define relative on all frames.
scale restrain 0.02 assumes expectation of about 2% change of relative
scale factor between frames, b restrain 0.2 assumes expectation of
b factor changing by 0.2A**2 between frames.
