helped Arn

Helped Arnold decipher some issues with double stars and Stellarium. About a dozen specific issues including elements of double stars not plotted or not listed. Pointed him to the WDS for official information. Helped him with the Greek letters with double star qualities. Also sorted a problem where when he used the Angle Measure tool, the position angle was constantly changed. I directed him to the settings. He must have turned on the horizontal option.
