I have trouble to analyze harp data with 0.5 velocity. Since the buffer 
problem the position information is missing, so I take a reconstruction 
for the index with the existed position information first(there still have 
some position information existed in the first steps), then I draw the 
picture with reconstructed index and peak. but seems it just moved to 70mm 
shown in reconstructed index and this is incorrect, it should be greater 
than 80mm(second picture of attachment). the difference of the total steps 
for each harp run before is larger than 0.5mm(sometimes 81.482155 
sometimes 81.993134) so I can not easily resize it to 81.5.
