Reduction Formulj^; and Instrumental Constants 



241 



Table 59 gives a condensed summary of the observed and computed data for the 

 adopted intensity-constants of sea deflector 4, used on Cruise II during April 1911 to 

 December 1913. This table is typical of the reductions made for each deflecting needle 

 and each deflection distance for the separate cruises. 



♦Stations so marked are locally disturbed. 

 'All values are based on C. I. W. Standards. 



2For the formula adopted from least^square adjustments, see Table 57, p. 238. 

 'The observations were made at Pamplemousses, stations B and C.

'There was a change in the condition of magnet 45 just before the shore observations at Antipolo and therefore a change 

 in the adopted formula for this magnet from Antipolo. (See p. 238.) . . „ . rr i 



«The observations were made at stations A and B on small coral island in Papeete Harbor.
