Rh common type of superficial damage, and is specifically designated where roofing material is stripped over an area of ap- proximately 40 square feet or more b. roof damage to wall-bearing buildings c. most purlin damage d.‘ partition (parti—wall) damage, if not load-bearing wall e. curtain-wall or panel-wall damage (e.g., the sheet metal wall of a steel frame building) f. broken windows g. gutted (burned-out) single—story, wall—bearing buildings. h. monitor distortion (because monitors are supported by roof trusses, a careful search should be made for struCtural damage). (damage assessment) suspect —- Evidence is insufficient to permit designation of a function with any degree of certainty, but photography or other informa— tion provides some indications of what the function may be.

tailings —— Processed waste refuse material separated as residue in the preparation of various products, as in milling of ore.

target -- A specified installation, object, ac- tivity, or geographic area of intelligence interest.

target area -- The environs of a target which might reasonably encompass associated ac- tivity.

target brief -— Consolidated reference, includ- ing photo, map, and collateral materials, machine processed on a given target for use by the photo interpreter preparingadescrip- tion of that target as seen on a particular mission for a first- or second-phase report.

target coverage —- Indication as to the partial or complete portrayal of a target on photog- raphy.

partial target coverage -— ,A target in ques- tion being less than totally portrayed in the photographic image. total target coverage —— A target in question being fully portrayed in the photographic image. (photographic interpretation),

thermal conduction -- The transfer of thermal energy from 1 part of an object to another. The transfer mechanism is molecular motion. (infrared). .

thermal convection -- The transfer of thermal energy from 1 place to another by actual motion of materials. The material motion is caused by differences in densities. (in- frared)

thermal radiation -- The term radiation refers to the continual radiation of energy from the surface of all objects above absolute zero. This energy is called radiant energy and is in the form of electromagnetic waves. These waves travel with the velocity of light and are transmitted through a vacuum as well as through air. (infrared)

third-phase report —— A comprehensive report based on and tailored to a specific require- ment presenting the results of a thorough analysis and a considered interpretation of all pertinent photography. (Third-phase reports produced by NPIC are the Detailed PIRs.)

total target coverage -- See target coverage.

track resolution -- See % resolution.

train -- The bombing system which involves the release of more than 1 bomb at a predetermined and selected interval, the latter being based on damage radius of the bomb against a particular target. The Brit- ish equivalent of this term is "stick."

transmission -— Passage through an object of that part of radiant energy which is not re- flected from or absorbed by the object.
