The data example used above has two intervals of good data separted by a long gap. Before doing further time analysis you may want to know the boundaries of these intervals.
input file: rp90_sti.qp
output file: rp90_tim.lis
xt> timfilter Input QPOE file: rp90_sti # the default extention, .qp, is known Output Time Filter List: rp90_tim
Start and stop times of data intervals are displayed on screen and written to the file rp90_tim.lis. To use multiple intervals in subsequent filtering run timfilter with parameter merge=yes. To use one interval, run the merge=no and uncomment.
Type help timfilter for instructions.
