The plot number on the section being processed 

 does not agree with the plot number on the 

 preceding PLOT OPTION CARD. Check data 

 sequencing .

See DIALEN 401 above. 



1204 



A card sequence error has been detected among 

 the dendrometer cards. Check data sequence.

Form factor of nonforked tree is suspiciously 

 large . 



In addition to the above errors, which will cause the offending tree to be skipped, 

 one message that may be printed in DIALEN may indicate erroneous data. DIALEN checks 

 that the length of each section is greater than 0.0001 foot. If not, the message: 



is printed \-iith the index of the section and its prior length inserted in place of I 

 and y, respectively. With dendrometry data, small negative lengths m.ay result from 

 small errors of measurement of closely spaced sections. In this case, if FLN(I) is 

 reasonably close to zero, the volume calculations should not be seriously affected. 

 Otherwise, the data sequencing and recording should be checked for errors.
