Table 8 Statistics of differences between the modeled geoidal heights and the measured geometric geoidal heights (unit: cm)

Model	Max	Min	Mean	RMS	Standard deviation
1500	36.5	−8.5	9.6	14.0	10.3
1500+a+o	32.7	−5.2	5.7	10.7	9.1
1500+a+o+t	17.2	−16.9	0.7	6.4	6.4
1500+a+o+t+l	7.7	−8.1	0.0	3.6	3.6
(Gravimetric geoid)	7.7	−8.1	0.0	3.6	3.6
1500+a+o+t+l+n	1.5	−1.1	0.0	0.4	0.4
(Hybrid geoid)	1.5	−1.1	0.0	0.4	0.4

Note: for the definitions of symbols a, o, t, and l, see Table 7; n represents geometric geoidal height
