52. You swung ship and compared the magnetic compass against the gyrocompass to find deviation. Gyro error is 2°E. The variation is 8°W. Find the deviation on a gyro heading of 037°.

Deviation is the difference between the magnetic heading and the compass reading, calculated as magnetic heading minus compass heading. Given a gyro heading of 037, a gyro error of 2E, and a variation of 8W, the deviation is 1W.
