Jack: I know the procedure to do it for WinTrak (that I use) is the same as some other packages, so I'm guessing that Nova is the same. Pretend the ALAT/ALON numbers are at a point on earth - you need to convert the coordinates to look like a point on the complete opposite side of the earth. So for ALAT (latitude), reverse the sign. If you were told 23, use -23. If you were told -5, use 5. For ALON, either add or subtract 180, so that you get some value between 0 and 359.999. If you were told 173, use 173+180 = 353. If you were told 257, use 257-180 = 77. The other option is to enter the numbers exactly as provided, which means the "perfect" squint angle is 180 degrees. 179 really means squint = 1, 178 means squint = 2, and so on.
