Rh  rendition of light and shade as the original subject.

possible (POSS) —- Evidence indicates that the designated function is reasonable and more likely than other functions considered.

Preliminary Mission Coverage Plot Summary (Pre MCPS) -— Acomposite graphic depicting the predicted areas of photographic coverage as determined from preliminary information.

Preliminary Photographic Evaluation Report (Pre PER) -— A cable—transmitted report conveying a preliminary estimate of the photo quality and success of a mission of photog— raphy, which is prepared at the processing site.

print —— A photographic copy made by projection or contact printing from aphotographic nega- tive or from a transparent drawing.

probable (P ROB) -— Evidence for the designated function is strong and other functions appear quite doubtful.

pseudostereoscopy -- An impression of 3—di- mensional relief derived by means of binoc— ular vision and the use of identical images.

psychochemical agent -- Achemical agent which affects the brain or nerve centers and by disorienting the human or animal mind pre— vents the mind temporarily from performing

its usual functions. (chemical warfare)

quay —- A wharf accommodating ships on 1 side only. Usually of solid construction, a quay is built against and parallel to shore, moles, or breakwaters.

radar resolution -— a. range resolution -— The minimum size of objects and the space between them that will show as separate re- turns on the radarscope when one object is farther than the other in range. b. track resolution (azimuth) —— The mini- mum size of objects and the space between

NPlC/R-282/65

them that will show when the targets are aligned parallel to the flight path.

radiance resolution —— The smallest detectable difference between the radiance of two regions of the object being imaged. Radiance resolu- tion is sometimes incorrectly called temper— ature resolution. (infrared)

rail—to—road transfer point —- A facility for the transfer of material from rail to road.

range resolution —— See ridgr resolution.

recognize -— To establish that an object, pat— tern, or installation under study on a photo- graph was known before.

reversed stereo —— See inverted stereo.

revet —— Bert] 1. To provide witharevetment, i.e., a wall or free embankment. 2. To face a wall, dike, river, bank, etc., with stone, brick, concrete, sandbags, or other material for purposes of preventing erosion or to hold earth slopes at steeper angles than could normally be maintained without caving or sliding.

revetment -— l. A wall, free embankment, or similar device, usually made of earth, de— signed to protect buildings, storage facilities, planes, vehicles, or weapons emplacements from the effects of blast, fire, bombs, straf- ing, or shellfire. 2. A facing or retaining wall.

rocket engine test facility —— An installation where the engine of a solid or liquid propul— sion rocket system is test fired.

roof disturbance —— Minor damage to the roof Without roof stripping in excess of 40 square feet. This is a minor type of damage which does not qualify as superficial damage; how- ever, it may be important where large areas are involved in damage to highly vulnerable contents such as precision instruments. (Roof disturbance does not mean roof distortion which is a clue to structural damage and which is more serious.) (damage assessment)

roof stripping -— See superficial damage.
