The phrase "axis was estimated" is correct and usable in written English.
It can be used in contexts involving measurements, calculations, or analyses where an axis is being assessed or approximated.
Example: "In the study, the axis was estimated based on the collected data points to determine the trend line."
Alternatives: "axis was calculated" or "axis was approximated."
Huge slip (> 50 m) on the plate interface up to the Japan Trench axis was estimated near the epicenter (~ 38.5°N) from seismic waves (Ide et al. 2011), inland and submarine geodetic data (Iinuma et al. 2012), and tsunami waveforms (Fujii et al. 2011; Satake et al. 2013b).
The extension of the body axis was estimated by measuring the angle formed by drawing white arrows connecting the front and back edges of the head and tail bud, respectively, to the center of the yolk as shown in Fig. 5K and L. A larger inward angle indicates shorter body axis.
Second, the long body axis was estimated as the best-fit line through three points: the mean of all the coxa-trochanter (CTr) point positions in both middle legs, the mean of the CTr points in both rear legs, and the mean of the ThC points in both front legs.
The angle between the stripes and the helical axis was estimated manually.
The mechanical axis was estimated by offsetting the anatomic axis by 2° (for women) and 4° (for men) [ 6].
The inter-transect mean of eigenvalues of the first axis was estimated for each collection site to represent the vegetation complexity.
Genetic parameters of production traits (growth, carcass yield, fillet yield) and bony tissues (head and vertebral axis) were estimated for large all-female rainbow trout Oncorhynchus mykiss reared in freshwater.
In this paper, linear and nonlinear coefficients of a low cost MEMS accelerometer (x axis) are estimated using continuous calibration method (using earth gravity vector (0 1g)) and centrifuge test (accelerations between 0 and 16g generated by the centrifuge).
At first, orthogonal 3 dominant axis are estimated from distribution of the normal vectors of input point cloud and all points are segmented to 3 groups associated with dominant axis.
Based on data from electron micrographs and crystal structures of various laminin domains, this axis is estimated to be 130 to 150 nm, while the horizontal axis, composed of the β2 and γ1 short arms, spans 70 to 80 nm (Beck et al., 1990; Yurchenco and Cheng, 1993; Sasaki et al., 2004).
The shrinkage along the z-axis was estimated by comparing the thickness of sections as they come off the microtome and after histological processing with Neurolucida.
