'You need to allow for an uncertainty of at least several metres.' In the case of the Mekong Delta, the real culprit proved to be the correct calibration point
. 'For elevation measurements, you always assume a pre-determined zero point.
That is the star itself, which you use as the first calibration point
. Move the mouse cursor to the spike's peak and click.
where ([X.sub.A], [Y.sub.A], [Z.sub.A]) and ([X.sub.B], [Y.sub.B], [Z.sub.B]) indicate the coordinates of calibration point
A and B.

Since analysis is dependent on sample size controlling the calibration point
time, flow and pressure, it is critical to choose the correct pressure-regulation device.
Wait for the electrode reading to stabilize before accepting each calibration point
To train each NN'S are used only those calibration points
of the group of the same type MS which belongs to a specific set, and are always located strictly the same way relative to the calibration point
which value will predict.
In Figure 8, [Q.sub.1] is setas a calibration point
. It is assumed that the coordinates of this calibration point
in the camera coordinate system are ([x.sub.1L][z.sub.1L]) and ([x.sub.IR][z.sub.IR]).
As the measurement does not have a true baseline or absolute calibration point
, it is unlikely to have a simple linear relationship with depth of anaesthesia.
If N samples are collected at each calibration point
, the [bar.[a.sub.ij]] is represented as
The calibration of megavoltage beams from linear accelerators has three essential requirements: (i) the use of an ion chamber with a calibration traceable to an SSDL; (ii) an accurate experimental setup; and, (iii) the correct interpretation of the dosimetry protocol to determine and correctly apply the factors to convert the charge reading to the absorbed dose in water at the calibration point
