Contents of Azimuth-Altitude Shading Table

I need to clarify how to represent a fully-shaded azimuth-altitude pair in the shading table. I am generating the file in a spreadsheet from data collected with the Theodolite iOS app, and importing as CSV. The instructions say the contents should be the percentage of shading. Do I enter that as 0 - 100, or 0 - 1? An unshaded entry is 0? Is there a sample file or even a screen capture I could get access to? I’ve tried several permutations, and none produce the results in the POS Results After Shading that I would have expected.

Unfortunately the Add a new file function below is not working (no error message provided, SAM 2015.1.30 Mac OS) or I would get you my SAM and CSV files.

Hello,
You should enter values between zero and 100, with zero being unshaded and 100% being fully shaded. You can find more details in SAM's Help system (click the Help button in the Edit Shading Data window).
If you continue having trouble, please [url=mailto:sam.support@nrel.gov?subject=PV%20Shading%20Files%20from%20Support%20Forum t=_self]email me your files[/url], and I'll try to help.
Best regards,

Thanks for the quick response. I made a few changes, but the most important I think was correcting the order of the altitude angle column in my spreadsheet. I had mine decreasing instead of increasing. The irradiance is dropping right where I expected it to now, so I think I’m OK.
