enter image description here

Line FB BB Declination
PQ 220∘30' 41∘15' 3∘30'E
QR 260∘45' 79∘30' 3∘30'E
RS 19∘30' 200∘ 3∘30'E
SP 100∘ 280∘ 3∘30'E

The difference of BB and FB of SP is 180O hence station S and P free from local attraction

  1. FB of PQ= 220∘30’, BB Of PQ= 41∘15’

    FB-BB= 220∘30’ - …
