. Computer Ephemeris. Lunar eclipse numerical map. Explanations. First portion of the page contains coordinates of sub-lunar points during the eclipse. Every point is represented with two numbers: geodetic longitude and geodetic latitude, both in degrees. Second portion of the page contains coordinates of the points at terminator line for the moments of contacts. There are 360 points on the lines, tens of them per line. The starting angle is indicated in the leftmost column.

... A hundred years later, a handful of Tunguska-sized asteroids have been spotted by telescopes, but most remain unseen.

... The current cable tray route specified in the UTE-FTT interface document MRO-ICD-EIE-0032d gives a length of 5.5m from the edge of the optical table to the bottom of Q5, the rack containing the FTT electronics. ... ACTION: - MRO will examine the cable route in detail and estimate the length of cable between the worst case camera position on the optical table and the position of the FTT space in Q5. ... Heat must be extracted from the camera's peltier cooler and also from the camera enclosure. ...

... Representing Coordinate Systems (Frames) While Mappings represent the relationships between coordinate systems, the coordinate systems themselves are represented by objects called Frames. ... A Plot's base Frame corresponds with the native coordinates of the underlying graphics system. Plotting operations are specified, using AST Plot methods, in physical coordinates which correspond with the Plot's current Frame (typically this might be a celestial coordinate system). ...

... The upward propagating HF wave is reflected at a particular height. ... The instabilities seen by the radar shortly after the HF is turned on can be divided into two types according to the degree of sophistication required in the model describing the response to the E field of the HF wave. ... The first kind occurs at a particular height determined by k vector and frequency matching conditions on the HF wave, the low and high frequency plasma waves, and the radar EM wave. ... Incoherent Scatter . ...

The Mars Flag reverse side is a continuation of the obverse side and not just a different design on the back and not a mirror image of the obverse. Main Flag Background Color . ...

... The original pro of used the fact that () any two such embeddings are related by isotopy and crossing changes, where edges are allowed to pass through each other. ... Lemma 5 is obviously false as stated: the sum should be over all unordered pairs of disjoint edges, i.e. it should be fact (), and this is what is assumed in the pro of. In the earlier argument, at the top of p.4, this do esn't matter because here, edges e and e that share a vertex automatically have lk (e, e ) = 0.) ...

A visual impression of the data used in the study. The relevant extra-galactic maps are represented as shells of increasing distance from Earth from left to right. ... After this are six shells containing maps of the millions of distant galaxies used in the study. These maps are produced using different telescopes in different wavelengths and are color-coded to show denser clumps of galaxies as red and less dense regions as blue. There are holes in the maps due to data quality cuts. ...

Unknown numbers are usually represented by letters of the alphabet . ... However, different letters are also used, often hinting at the quantity they represent-- v for an unknown velocity, T for an unknown time, m or M for unknown masses and F for an unknown force. ... An example of case (#1) is the ratio between the length of a circle and its diameter, a universal constant appearing in many equations (for example, Kepler's equation in section (12a)), whose value to 11 decimals is 3.14159265359.. ...
