In the worksheet on page 46, in line 2-5, the DR longitude is entered as 133 degrees 49.0 minutes. This is far from the DR longitude used for the Vega and Venus sights of 134 degrees 11 minutes. Since the time of the Polaris sight was 12:45:03 (GMT) the assumed longitude should be 134 degrees 11 minutes. How was the 49 minute value arrived at?

Thank you

Again you have an out-dated copy. The current copy has 134° 11' NOT the 133° 49.0'.
