The AFD directions show that both inclination and declination appear to reverse polarity at approximately 2 m below the Byk-E tephra, as previous studies have found (Niitsuma 1971; Okada and Niitsuma 1989).
In other words, even for a subtle shift in angular declination, both explicit (verbal estimation) and implicit (walked distance) measures of perceived distance can detect the effect of angular declination on perceived distance when scaling variance is made irrelevant.
Transit circles and horizontal meridian circles measure both right ascension and declination at the same time.
Both the main field declination D and the horizontal component H were scaled up by a factor of 2 in order to match the scale of the bar chart, while the secular variation for D was scaled by 4 Fig. 3 Contour plot of the misfit of IGRF-12 to Southern African declination (D) observations after subtracting crustal anomalies (MF7) and external field variations as determined by the CM4 model.
The transit circle was capable of determining both right ascension and declination of a star, unlike the more simple and common transit instrument that can only determine the right ascension.
Those humans with a posteriorly directed tibial arch angle (8%) have significantly lower talocalcaneal and talar declination angles, both measures of an asymptomatic flatfoot.
The data and model qualitatively agree; and indicate that depending on longitudes both the displacement of the equators and declination angle are important in producing the north south asymmetry though the displacement of the equators seems most effective.
Their major findings about WSA formation are as follows: the equatorward neutral wind is the critical driver, the plasmaspheric downward flux is another driver but not a critical one, and both the magnetic offset and the declination of the magnetic field are very important.
Using the measurements from the Toronto and Hobart sites, Sabine noticed both short-term fluctuations in magnetic declination over a period of hours, and longer-term variations over months.
Results show that for nearly all seasons from 2001 to 2010 and in both sides of the longitudes with zero declination, there exist systematic differences for the mid-latitude ionospheric TEC in the regions mentioned above and the features of these differences markedly depend upon the local time but less depend upon seasons and the level of solar activity.
