eric, the problem was the X2 var in bit unpacking rountine can be a missing value if all bits are set to 1's. it's not apparent from the docs about this case. so now the ds.mint.bin file can be decoded correctly. i need to check the other files. the ds.sky.bin file with proj 10 needs to have the proj 10 code implemented. do you know of any java coding of proj 10? if not, how about c code. it will probably be awhile before i have the time to look at proj 10. robb...
