Fixed to send in offset to find_intensity_keys() which allow system test to pass.
Regarding bug #21344, (https://gna.org/bugs/index.php?21344) - Handling of in sparse acquired R1rho dataset with missing combinations of time and spin-lock field strengths.
This is the first fix to allow system test to pass: relax -s Relax_disp.test_bug_21344_sparse_time_spinlock_acquired_r1rho_fail_relax_disp
A better solution is described in: http://thread.gmane.org/gmane.science.nmr.relax.devel/5107 which will be implemented.
