Usage (this text can be obtained with xdscc12 -h):
deltacc12 -dmin <lowres> -dmax <highres> -nbin <nbin> -mode <1 or 2> -< abcdeftwz> FILE_NAME
dmax (default 999A), dmin (default 1A) and nbin (default 10) have the usual meanings.
mode can be 1 (equal volumes of resolution shells) or 2 (increasing volumes; default).
-t: total oscillation (degree) to batch fine-sliced frames into
other options can be combined (e.g. -def), and switch the following off:
-a: individual isomorphous summary values
The program output is terse but supposed to be self-explanatory. Part of it is most easily visualized via XDSGUI, however, that currently deals with the isomorphous signal of a batch of frames (width chosen with the -t option) relative to all data.
For multiple datasets, the output lines show the contribution of each dataset toward the total CC<sub>1/2</sub>. Negative numbers indicate a worsening of the overall signal.
