The help is incomplete then. They appear to be relying on the supporting "Output coordinate system" as set in the Environments tab (my bad... forgot to check it too).

Strangely... I read that help topic that the default output coordinate system is WGS84, BUT if the "Input" coordinate is not that, then you need to specify it first. It doesn't say anything about projecting the data to your desired coordinate system.

Thank you for this post Scott Drzyzga‌. This problem was brought to the development team a few weeks ago and has been fixed in ArcGIS Pro 2.6 (it will be in the early adopter snapshot of ArcGIS Pro 2.6, or the public beta available in a few months if you would want to participate). For the 2.5.x release you will need to perform the additional step you explained with the Project (management) tool.

Assuming a convergence ratio in the image field of an aplanatic optical system (light intensity converging on an airy disc) as 100%, the convergence ratio in an optical system with an aberration is referred to as a "Strehl Ratio (SR)". As shown in the graph in Figure 2, an optical system with a higher SR value is closer to an aplanatic optical system.

A Strehl ratio of 80% is commonly known as the diffraction limit. An objective lens below this limit is not assumed to have satisfactory performance. An objective lens with a Strehl ratio of more than 95% compares favorably with an aplanatic lens in performance for common observations.

When a point light source is observed, an aplanatic optical system concentrates a light beam into one point at the image location. Contrarily, an optical system with aberration does not concentrate the beam into a point, resulting in a divergence. Figure 1 shows the appearances of a point image (intensity distribution of a point image) in both optical systems.

Dan, this is a workflow I've been using for years that is now generating unexpected behavior. I did specify both the input and the output SRS (see the figures in my post). The error literally occurs when I specify both (as one should if the desired output is different from the input). The reason I am posting is because this error did not occur in prior versions of ArcGIS Pro and is occurring now.

I have three (3) CSV formatted files containing geographic coordinates (I attached one). When I use XY Table to Point to create point features from any of them, I cannot get valid results if I set both the input SRS and the output SRS (via the Environment settings). In my case, the input SRS is WGS84; the desired output SRS is NAD83-2011 State Plane CA-II (0402).

on pro 2.9 i have got some issues too with this tool. The parameter of the tool "coordinate system" goes suddendly wrong without any manual update on the stuff.

The XY Table to Point tool does create points, but it misinterprets the desired output SRS as the defined input SRS and, so, plots all the points near the false origin of the CA-II coordinate system (i.e., out in the Pacific Ocean).

I now have to use a two-step process to accomplish what used to be a one-step process: 1) use XY Table to Point to create point features tied to the input SRS; then 2) use the Project tool to handle the coordinate conversion.

Note: A laser interferometer is used for actual optical performance evaluations, thus providing evaluation with a single wavelength. Unless otherwise noted, Olympus offers Strehl ratio values measured with the e-line laser (544nm).
