input data precision

2007-10-24 Thread Douglas Kojetin
Hi, How important is precision for the input relaxation data (r1, r2, noe) for relax analysis? My values were calculated using curvefit, with values using 4 decimal places. On the other hand, relax curve fitting produces rates with many more decimal places (16). Thanks, Doug
