Question: Where is the continental limit on the continent which contains Robert Point?

full_context: Document 1: Sadala Point: Sadala Point (, ‘Nos Sadala’ \'nos sa-'da-la\) is a point on the southeast coast of Robert Island in the South Shetland Islands, Antarctica projecting 500 m into Bransfield Strait. Situated 2.43 km northeast of the southeast extremity of Robert Point, 2.97 km south-southwest of Batuliya Point and 4.8 km south-southwest of Kitchen Point.
Document 2: Rowe Point: Rowe Point is a sharp, low ice-free point at the northeast extremity of Ivanov Beach on the southeast coast of Barclay Bay in western Livingston Island in the South Shetland Islands, Antarctica.
Document 3: Newell Point: Newell Point is the rocky point forming the northeast extremity of Robert Island in the South Shetland Islands, Antarctica and is a northwest entrance point of Nelson Strait.
Document 4: Antarctica: Emilio Marcos Palma was the first person born south of the 60th parallel south (the continental limit according to the Antarctic Treaty), as well as the first one born on the Antarctic mainland, in 1978 at Base Esperanza, on the tip of the Antarctic Peninsula; his parents were sent there along with seven other families by the Argentine government to determine if the continent was suitable for family life. In 1984, Juan Pablo Camacho was born at the Frei Montalva Station, becoming the first Chilean born in Antarctica. Several bases are now home to families with children attending schools at the station. As of 2009, eleven children were born in Antarctica (south of the 60th parallel south): eight at the Argentine Esperanza Base and three at the Chilean Frei Montalva Station.
Document 5: Robert Point: Robert Point is a rocky point at the end of a small peninsula projecting 2.7 km into Bransfield Strait from the southeast coast of Robert Island in the South Shetland Islands, Antarctica to form the east side of the entrance to Devesil Bight.
Document 6: Antarctica: New claims on Antarctica have been suspended since 1959 although Norway in 2015 formally defined Queen Maud Land as including the unclaimed area between it and the South Pole. Antarctica's status is regulated by the 1959 Antarctic Treaty and other related agreements, collectively called the Antarctic Treaty System. Antarctica is defined as all land and ice shelves south of 60° S for the purposes of the Treaty System. The treaty was signed by twelve countries including the Soviet Union (and later Russia), the United Kingdom, Argentina, Chile, Australia, and the United States. It set aside Antarctica as a scientific preserve, established freedom of scientific investigation and environmental protection, and banned military activity on Antarctica. This was the first arms control agreement established during the Cold War.
Document 7: Esteverena Point: Esteverena Point is the rocky point projecting 700 m into Boyd Strait to form the west extremity of Snow Island in the South Shetland Islands, Antarctica. The feature is named by Argentina.
Document 8: Byewater Point: Byewater Point is the rocky point forming the northwest extremity of Snow Island in the South Shetland Islands, Antarctica. It is a north entrance point for Boyd Strait. The area was visited by 19th century sealers.
Document 9: Antarctic Peninsula: The Antarctic Peninsula, known as O'Higgins Land in Chile, Tierra de San Martin in Argentina, and originally known as the Palmer Peninsula in the US and as Graham Land in Great Britain, is the northernmost part of the mainland of Antarctica, located at the base of the Southern Hemisphere.
Document 10: Chinstrap Point: Chinstrap Point is the southeast point of Vindication Island, South Sandwich Islands. This feature was named Rocky Point during a survey of the island from RRS "Discovery II" in 1930, but the name was changed to avoid duplication. The new name applied by the UK Antarctic Place-Names Committee in 1971 refers to the enormous colony of chinstrap penguins on the point.
Document 11: Antarctica: The first semi-permanent inhabitants of regions near Antarctica (areas situated south of the Antarctic Convergence) were British and American sealers who used to spend a year or more on South Georgia, from 1786 onward. During the whaling era, which lasted until 1966, the population of that island varied from over 1,000 in the summer (over 2,000 in some years) to some 200 in the winter. Most of the whalers were Norwegian, with an increasing proportion of Britons. The settlements included Grytviken, Leith Harbour, King Edward Point, Stromness, Husvik, Prince Olav Harbour, Ocean Harbour and Godthul. Managers and other senior officers of the whaling stations often lived together with their families. Among them was the founder of Grytviken, Captain Carl Anton Larsen, a prominent Norwegian whaler and explorer who, along with his family, adopted British citizenship in 1910.
Document 12: Emilio Palma: Emilio Marcos Palma (born 7 January 1978) is an Argentine man known for being the first documented person born on the continent of Antarctica.
Document 13: Chileans: Though the majority of Chileans reside in Chile, significant communities have been established in multiple countries, most noticeably Argentina, United States, Australia and Canada and countries of the European Union. Although small in number, Chilean people also make up a substantial part of the permanent population of Antarctica and the Falkland Islands (see: Chileans in the Falkland Islands).
Document 14: Islands Point: Islands Point () is a high rock point separating Berg Bay and Relay Bay, lying along the west shore of Robertson Bay in Victoria Land, Antarctica. The headland was charted by the northern party of the British Antarctic Expedition, 1910–13, under Captain Robert Falcon Scott, and was probably named with reference to the small island (Sphinx Rock) which lies just north of the point. The headland lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 15: Antarctica: Several governments maintain permanent manned research stations on the continent. The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1,000 in winter to about 5,000 in the summer, giving it a population density between 70 and 350 inhabitants per million square kilometres (180 and 900 per million square miles) at these times. Many of the stations are staffed year-round, the winter-over personnel typically arriving from their home countries for a one-year assignment. An Orthodox church—Trinity Church, opened in 2004 at the Russian Bellingshausen Station—is manned year-round by one or two priests, who are similarly rotated every year.
