latitude

 [lat´ĭ-tood]
the recording capability of x-ray film.
contrast latitude the ability of a film to record differences in density.
film latitude the ability of an emulsion to record a wide range of densities.

lat·i·tude

(la'ti-tūd),
The range of light or x-ray exposure acceptable with a given photographic emulsion. See: latitude film.
[L. latitudo, width, fr. latus, wide]

latitude

Etymology: L, latitudio, breadth
the ability of an x-ray imaging system to produce acceptable images over a range of exposures. If a system has wide latitude, it is possible to image parts of the body that vary in thickness or density with only one exposure. A system of lesser latitude would require a lower exposure over the thin section and a greater exposure where the absorption was greater.

The range of light or x-ray exposure acceptable with a given photographic emulsion.

latitude (lat´itood),

n the range between the minimum and maximum film exposures to radiation that yields images of structures of which photographic density differences are discernible under normal viewing conditions. Latitude mainly varies directly with kilovoltage and inversely with contrast. See also contrast.

The Court thus concludes that the starting-point of the maritime boundary between the Parties is the intersection of the parallel of latitude passing through Boundary Marker No.
Decides that the initial segment of the single maritime boundary follows the parallel of latitude passing through Boundary Marker No.
The single maritime boundary between the Parties starts at the intersection of the parallel of latitude passing through Boundary Marker No.
While concurring with the findings that the starting-point of the single maritime boundary delimiting the respective maritime areas between the Republic of Peru and the Republic of Chile is the intersection of the parallel of latitude passing through Boundary Marker No.
And the fundamental point is that the 1954 Agreement on a Special Zone, which is deemed to be an integral and complementary part of the Santiago Declaration, confirms the existence of the maritime boundary between the two countries, along the parallel of latitude.
Not having been able to support the conclusion of the majority that the agreed maritime boundary, which follows the parallel of latitude passing through Boundary Marker No.
In my view, the record does not support the conclusion that, by the time the 1954 Special Maritime Frontier Zone Agreement (henceforth, the 1954 Agreement) was adopted, a maritime boundary was already in existence along a parallel of latitude between Peru and Chile.
Contrary to what the Court asserts in the Judgment, the language of the 1954 Agreement cannot be said to have clearly acknowledged the existence of an all-purpose maritime boundary along the parallel of latitude beyond a distance of 12 nautical miles from the coast (Judgment, paragraphs 90 and 102).
Those provisions (which, as the Court notes, contain no indication of the nature or extent of a maritime boundary) were aimed at dealing with small fishing boats accidentally straying into waters on either side of those provisional lines, and cannot easily be construed as clearly confirming the existence of a tacit agreement in respect of a permanent, all-purpose international maritime boundary along a parallel of latitude beyond a distance of 12 nautical miles from the coast.
While certain documents and/or events that were considered by the Court may be said to reflect some degree of the Parties' shared understanding that there was a "maritime boundary" in place between them along the parallel of latitude passing through the coastal terminus of their land boundary, there are others that could equally be said to demonstrate the absence of such an agreement.
The boundary recognized in those texts follows the parallel of latitude passing through boundary marker No.
The 1954 Agreement and the 1968-1969 arrangements essentially concerned fishing by small vessels close to the coast, and Chile has failed to show that the boundary whose existence was recognized by the Parties in those texts extended along the parallel of latitude beyond the area in which those vessels operated.
