rotTelPos not in columnMap #40

Closed jmeyers314 closed 8 years ago

jmeyers314 commented 8 years ago

I'm trying to investigate the AngularSpreadMetric contributed here on the distribution of camera rotator angles with respect to zenith. This website leads me to believe that this should be as simple as replacing the rotSkyPos argument in the Angular Spread jupyter notebook in this repo (which runs fine) with rotTelPos. When I try this though, I get the error 'rotTelPos not in columnMap'.

I suppose this is because one can easily compute rotTelPos from rotSkyPos and the parallactic angle PA, but I haven't been able to find the appropriate Stacker so far. Does it exist? or am I on the wrong track entirely?

Hi Josh,

rotTelPos looks like it is actually in the current summary table (I think there may have been a brief period where it wasn't), so this should work. Can you check your capitalization? The column names are case sensitive. If that doesn't work, just double check.. Open the file with sqlite and do a query to check rotTelPos is available in the summary table, like :

sqlite3 minion_1016_sqlite.db

select rotTelPos from summary limit 1;

Thanks Lynne, I was still on enigma_1189. After upgrading to minion_1016 everything works. Closing this issue. -Josh
