Etymology


The names Tunjuelo and Tunjuelito ("little Tunjuelo") are derived from the Cerro de los Tunjos, also Los Tunjos Lake, named after the tunjos, the religious votive figurines of the indigenous language of the Muisca, who inhabited the Bogotá savanna before the Spanish conquest.[1]

Source and mouth of the Tunjuelo River on the Bogotá savanna


The Tunjuelo River has a total length of 73 kilometres (45 mi) and originates in the Sumapaz Páramo, in the southern part of Bogotá.[2] It flows through the southern part of the Colombian capital, south of the Fucha River, and has the largest drainage basin of the rivers of Bogotá.[3] The river flows through the Usme Synclinal, where the type localities of various geological formations (among others the Marichuela Formation) are situated. The Tunjuelo River forms the border between the localities Usme and Ciudad Bolivar and between the namesake locality Tunjuelito and Ciudad Bolívar. The Tunjuelo River is highly contaminated.[4]

Understanding the information contained in the Deep Space Network XML data?

Image
up vote 1 down vote favorite NASA's Deep Space Network activity can be viewed conveniently at https://eyes.nasa.gov/dsn/dsn.html but if you would like data in a more raw XML form, it can be accessed as described in this answer Below is a small Python script that reads the XML into a list of dictionaries, and saves it to disk as a JSON. The dictionaries are organized at the higher level by dish, then by spacecraft per dish. Question: What are the most-likely meanings of all the data field contained in the Deep Space Network XML data?
