Question: What constellation, containing Megrez, is on the Alaskan Flag?

full_context: Document 1: Ursa Minor: Ursa Minor (Latin: "Lesser Bear", contrasting with Ursa Major), also known as the Little Bear, is a constellation in the Northern Sky. Like the Great Bear, the tail of the Little Bear may also be seen as the handle of a ladle, hence the North American name, Little Dipper: seven stars with four in its bowl like its partner the Big Dipper. It was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and remains one of the 88 modern constellations. Ursa Minor has traditionally been important for navigation, particularly by mariners, because of Polaris being the North Star.
Document 2: Beta Ursae Minoris: Beta Ursae Minoris (β Ursae Minoris, abbreviated Beta UMi, β UMi), also named Kochab, is the brightest star in the bowl of the Little Dipper asterism (which is part of the constellation of Ursa Minor), and only slightly fainter than Polaris, the northern pole star and brightest star in Ursa Minor. Kochab is 16 degrees from Polaris and has an apparent visual magnitude of 2.08. The distance to this star from the Sun can be deduced from the parallax measurements made during the Hipparcos mission, yielding a value of 130.9 ly .
Document 3: Flag of the United States: The flag of the United States of America, often referred to as the American flag, is the national flag of the United States. It consists of thirteen equal horizontal stripes of red (top and bottom) alternating with white, with a blue rectangle in the canton (referred to specifically as the "union") bearing fifty small, white, five-pointed stars arranged in nine offset horizontal rows, where rows of six stars (top and bottom) alternate with rows of five stars. The 50 stars on the flag represent the 50 states of the United States of America, and the 13 stripes represent the thirteen British colonies that declared independence from the Kingdom of Great Britain, and became the first states in the U.S. Nicknames for the flag include The Stars and Stripes, Old Glory, and The Star-Spangled Banner.
Document 4: Ursa Major II Dwarf: Ursa Major II Dwarf (UMa II dSph) is a dwarf spheroidal galaxy situated in the Ursa Major constellation and discovered in 2006 in the data obtained by the Sloan Digital Sky Survey. The galaxy is located approximately 30 kpc from the Sun and moves towards the Sun with the velocity of about 116 km/s. It is classified as a dwarf spheroidal galaxy (dSph) meaning that it has an elliptical (ratio of axes ~ 2:1) shape with the half-light radius of about 140 pc.
Document 5: Flag of Alaska: The flag of Alaska consists of eight gold stars, forming the Big Dipper and Polaris, on a dark blue field.
Document 6: Canes Venatici: Canes Venatici is one of the 88 official modern constellations. It is a small northern constellation that was created by Johannes Hevelius in the 17th century. Its name is Latin for "hunting dogs", and the constellation is often depicted in illustrations as representing the dogs of Boötes the Herdsman, a neighboring constellation. Cor Caroli is the constellation's brightest star, with an apparent magnitude of 2.9. La Superba is one of the reddest stars in the sky and one of the brightest carbon stars. The Whirlpool Galaxy is a spiral galaxy tilted face-on to observers on Earth, and was the first galaxy whose spiral nature was discerned.
Document 7: Delta Ursae Majoris: Delta Ursae Majoris (δ Ursae Majoris, abbreviated Delta UMa, δ UMa), also named Megrez, is a star in the northern circumpolar constellation of Ursa Major. With an apparent magnitude of +3.3, it is the dimmest of the seven stars in the Big Dipper asterism. Parallax measurements yield a distance estimate of 58.4 ly from the Sun.
Document 8: USS Megrez (AK-126): USS "Megrez" (AK-126) was a "Crater"-class cargo ship commissioned by the US Navy for service in World War II. "Megrez" was named after Megrez, a star in the constellation Ursa Major. She was responsible for delivering troops, goods and equipment to locations in the Asiatic-Pacific Theater.
Document 9: Centaurus: Centaurus is a bright constellation in the southern sky. One of the largest constellations, Centaurus was included among the 48 constellations listed by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations. In Greek mythology, Centaurus represents a centaur; a creature that is half human, half horse (another constellation named after a centaur is one from the zodiac: Sagittarius). Notable stars include Alpha Centauri, the nearest star system to the Solar System, its neighbour in the sky Beta Centauri, and V766 Centauri, one of the largest stars yet discovered. The constellation also contains Omega Centauri, the brightest globular cluster as visible from Earth and one of the largest known.
Document 10: Flag of Arkansas: The flag of Arkansas, also known as the Arkansas flag, consists of a red field charged with a large blue-bordered white lozenge (or diamond). Twenty-nine five-pointed stars appear on the flag: twenty-five small white stars within the blue border, and four larger blue stars in the white diamond. The inscription "ARKANSAS" appears in blue within the white lozenge, with one star above and three stars below. The star above and the two outer stars below point upwards; the inner star below points downwards. The flag was designed by Willie Hocker of Jefferson County, a member of the Pine Bluff Chapter, Daughters of the American Revolution.
Document 11: Ke Kā o Makali‘i: Ke Kā o Makali‘i is a Polynesian constellation consisting of five stars in a curving formation in the shape of a bailer surrounding the western constellation orion. The constellation is seen to rise in the east like a cup and set in the west pouring onto the western horizon.
Document 12: Big Dipper: The Big Dipper (US) or the Plough (UK) is an asterism consisting of seven bright stars of the constellation Ursa Major; six of them are of second magnitude and one, Megrez (δ), of third magnitude. Four define a "bowl" or "body" and three define a "handle" or "head". It is recognized as a distinct grouping in many cultures.
Document 13: Northern Pole: Northern Pole (北极 in Simplified Chinese, "běi jí" in Pinyin) is a traditional Chinese asterism found in the Purple Forbidden enclosure (紫微垣 in Simplified Chinese, "zǐ wēi yuán" in Pinyin). It consists of five stars found in the modern constellations of Ursa Minor and Camelopardalis and represents the five stars of the North Pole. During the Qing dynasty, a total of four stars from the constellation Ursa Minor was added to the asterism.
Document 14: Dao Look Gai (Thai Folk Tale): Dao Look Gai, also known as the Chick Stars or Pleiades (M45), is a Thai folk tale from Surin province, in northeastern Thailand. It is a fable that explains why Pleiades is called Dao Look Gai (In Thai language, “Dao” means star and “Look Gai” means chick) and why it has 7 stars in the sky.
