[molpro-user] threshhold for MULTI

Hi everyone,
I just found a problem about the accuracy in the MULTI convergency.
The default threshhold for orbital gradient, change of total energy,
size of step is 1.d-2, 1.d-6, 1.d-3, respectively, as shown in p144 of
2010 version manule.
In my casscf optimzation calculation, I did not give any keyword to
set the accuracy. But the output file show different ones for the
first iteration of MULTI calculation as follows:
Convergence thresholds 0.10E-01 (gradient) 0.23E-05 (energy)
0.10E-02 (step length)
and the log file give another different accuracy as follows:
Convergence thresholds 0.10E-05 (gradient) 0.10E-07 (energy)
0.10E-02 (step length)
Does anyone have similar problem? Any suggestions are welcome.
Thanks,
lydia
