from previous efforts posted it was suggested it could be done a bit better,
http://www.iceinspace.com.au/forum/s...ad.php?t=34261 so i have reworked the data...... i think its better now, after 5-6 hrs at the computer i hope so. im sure you will let me know where it needs to go from here, after very litttle imaging for the best part of 3 months ive gotten out of touch, so thanks for the prompt to do it again.
cheers clive
