hour angle उदाहरण वाक्य
उदाहरण वाक्य
- Replace " ? " 2 with declination and longitude difference with hour angle, and change the sign ( since the hour angle is positive westward instead of east ).
- Using a nautical almanac, the declination ( celestial latitude ), and the Greenwich hour angle ( celestial longitude ) are obtained of the observed object for the time of observation.
- At solar noon the hour angle is 0.000 degree, with the time before solar noon expressed as negative degrees, and the local time after solar noon expressed as positive degrees.
- Positions on the celestial sphere are often expressed using two coordinates : declination and sidereal hour angle, which are similar to latitude and longitude on the surface of the Earth.
- The Capuchin sundials are constructed and used graphically, as opposed the direct hour-angle measurements of horizontal or equatorial dials; or the calculated hour angle lines of some altitude and azimuth dials.
- The 75-year-old angler, who stays in fishing shape by bicycling and skiing on a regular basis, was also unaware of the new DFG regulation that allows 24-hour angling in Mono County.
- Note that H _ \ text { RD } advances anticlockwise with respect to the zero hour angle for those dials that are partly south-facing and clockwise for those that are north-facing.
- Sidereal hour angle is a measurement between 0 and 360 degrees, indicating how far west a body is from an arbitrarily chosen point on the celestial sphere called the First Point of Aries.
- If time was short this orientation usually used an integral compass, but was updated by calculation ( azimuth by hour angle or azimuth by Polaris ) or'carried'by survey techniques from a survey control point.
- The actual declination and hour angle of the celestial body are found from astronomical tables for the time of the measurement and together with the'True Altitude'are put into a formula with the assumed latitude.
