     79'''Sync'''
     80
     81If you get something in the log file like:
     82
     83** End of POSATT file with NO Specim sync found[[BR]]
     84**     no sync within 5.00 secs of raw file header time: 49915.66
     85
     86then there is no sync info in the nav file for that line and and the range of possible sct values will increase (up to a few seconds). You will need to include 'has_sync = false' in the config file line entry and input a wider range of scts, e.g.
     87
     88[hawk_-11] [[BR]]
     89...[[BR]]
     90...[[BR]]
     91...[[BR]]
     92has_sync = false[[BR]]
     93sctend = -1[[BR]]
     94sctincrement = -0.1[[BR]]
     95sctstart = 1[[BR]]
     96
     97[hawk_-12][[BR]]
     98...
     99
     100'''Turns'''
     101
     102If you get something in the log file like:
     103
     104** flight line may have a turn in it **[[BR]]
     105** heading spread over approximately:  120 degs **
     106
     107** run terminated due to turn **
     108
     109then there is a bend in the line that is too sharp. You need to add a -bend flag to the azcorr arguments for the line entry in the config file, e.g.
     110
     111[eagle_-7][[BR]]
     112...[[BR]]
     113...[[BR]]
     114...[[BR]]
     115azgcorr_args_extra = -bend
     116
     117[eagle_-8][[BR]]
     118...
     119
     120Once processed, it is best to exclude the lines which are causing the problems by including a -l flag in azspec followed by the line numbers delineating the part of the line you want to keep, then reprocessing. E.g. if the bend is at the start of the line:
     121
     122
     123[eagle_-7][[BR]]
     124...[[BR]]
     125...[[BR]]
     126...[[BR]]
     127azgcorr_args_extra = -bend[[BR]]
     128azspec_args_extra = -l 50 2000
     129
     130will exclude the first 50 lines.
