A ring has two size markings in millimeter such as 28mm-37mm, 49mm-52mm, 77mm-72mm and so on. The first number is the size of the thread that is closer to the camera lens (i.e. , the male thread), while the second is the size of the thread of the farther end (i.e. , the female thread). Therefore, a step-up ring with marking 43mm-49mm means the male and female thread sizes are 43mm and 49mm, respectively.
Some forms of ordination analysis, classical or canonical, are widely used by palaeolimnologists. as tools in the handling, summarisation, and interpretation of palaeolimnological data, either modern assemblages or. core fossil assemblages.
Note that, as the cogging torque is obtained from a non-exited case, there is no need for a current to be given at this step. The next analysis, the static torque vs. angle for a range of currents, will also use the DC_ST analysis. The simulation step can be coarser in this case and the analysis is done over 90.
