+ | ===== The sectorfile latitude/longitude overflow bug ===== | ||
+ | |||
+ | |||
+ | |||
+ | Keep a sharp lookout for a major bug in latitude and longitude coordinates which originate from IvAc v1 sectorfiles created with the old //sector file creator website//. Apparently IVAC v1 did not care about this error and just used the data regardless of the overflow value. | ||
+ | |||
+ | |||
+ | You often see coordinates like: | ||
+ | |||
+ | W0023260000 -> 002:32:60.000 | ||
+ | |||
+ | Notice the overflow value in the seconds part: **60 seconds** ?! | ||
+ | |||
+ | 60 seconds = 1 minute .... The maximum seconds value should be 59.999 seconds - so we have an overflow issue: | ||
+ | |||
+ | 002:32:60.000 should be corrected to 002:33:00.000 | ||
+ | |||
+ | |||
+ | You will also find coordinates like E0082339001 ending in '1'. These are also calculation errors and can be safely set to '0' | ||
+ | |||
+ | E0082339001 -> E0082339000 | ||
+ | |||
+ | |||
+ | |||
+ | ==== How to find any occurences of the bug? ==== | ||
+ | |||
+ | |||
+ | |||
+ | Check the log file for errors in *log/ivac.log* for an overflow error similar to: | ||
+ | |||
+ | ERROR Java2D Queue Flusher ... out of range:E0023260000 | ||
+ | |||
+ | Simply use your text editor to search for the listed coordinate. | ||
