Webel «pa» Parsing Analysis Diagrams (PADs) are "scratchpads" used to elicit model elements traceably from text Snippets (extracts from source Documents). While BDDs are a good initial choice, most types of SysML diagram can be used as a «pa» diagram.

Webel Parsing Analysis: Acronym: PAD = Parsing Analysis Diagram (may be nearly any diagram type, except those types that must be owned by an elicited model element)
Webel Parsing Analysis: As StateMachine Diagrams are always owned by an element that is not eventually under the Source Input Zone they should not be used as «pa» diagrams. Elicit States instead via the /member section of the specification dialog.

Our first Parsing Analysis diagram about telescopes
The first known practical telescopes were refracting telescopes
The reflecting telescope uses mirrors to collect and focus light
Many new types of telescopes were invented including radio telescopes and infrared telescopes
Optical radiation, visible, UV, and infrared
Radio frequencies (just a quick look)
An optical telescope is a telescope that gathers and focuses light mainly from the visible part of the electromagnetic spectrum
The objective is the optical element that gathers light from the object being observed and focuses the light rays
An eyepiece is a type of lens that is attached to a variety of optical devices such as telescopes and microscopes.
Most (but not all) telescope designs produce an inverted image at the focal plane
Optics: real images vs virtual images and focus points
An object infinitely far from the optical system forms an image at the rear focal plane
The basic scheme of an optical telescope: Keplerian refractor
A curved primary mirror is the reflector telescope's basic optical element
The Gregorian telescope employs a concave secondary mirror that reflects the image back through a hole in the primary mirror.
The Newtonian telescope has flat secondary mirror and a paraboloid or spherical primary mirror
The classic Cassegrain telescope has a parabolic primary mirror and a hyperbolic secondary mirror

[POLICY, STYLE]{STRICT} Webel Parsing Analysis «pa» diagrams are NOT intended as final presentation diagrams! They serve merely to traceably elicit model elements, which may then be shown in other (typically much tidier) presentation diagrams elsewhere.
[DISPLAY, MODELLING, POLICY]{STRONG} Webel Parsing Analysis: A "focus" Parsing Analysis Diagram (PAD) for one or more Snippets SHOULD always show the /member tagged value of every Snippet.
