... Meade Instruments Corporation . ... Meade Pictor XT-Series CCD Autoguider/Imagers . ... Take new sets of calibration frames if the temperature changes significantly.(or change the set you are using or the scaling if you are reusing calibration frames). ... You can also use scaleable dark frames called thermal frames. ... However, if you wish to reuse dark frames with images of different exposure times, you must turn the dark frame into a thermal frame by subtracting the bias information. ...
NASA s Solar Dynamics Observatory captured this image of Earth and the Moon transiting the Sun together on September 13, 2015. The edge of Earth, visible near the top of the frame, appears fuzzy because Earth s atmosphere blocks different amounts of light at different altitudes. On the left, the Moon s edge is perfectly crisp because it has no atmosphere. This image was taken in extreme ultraviolet wavelengths of 171 angstroms. ... NASA/SDO ...

The program provides possibility to browse the full session telemetry data, perform geographical referencing of the telemetry, select a fragment of arbitrary size (fragments of юVHHR , HIRS instruments data for a region of user’s interest, along with acqiusition time data per telemetry line), perform calibration of HIRS data. ... The fragmented data can be mapped to geographic coordinates using satellite orbit data. ...

PENTICTON SOLAR RADIO FLUX VALUES (from SGD Explanation of Data Reports) Daily Solar Flux Values - Penticton -- Daily measurements of the integrated emission from the solar disc at 2800MHz (10.7cm wavelength) have been made by the National Research Council of Canada since 1947. ... The data are tabulated in two forms: the "observed flux" (S), and the "adjusted flux" (Sa). ... The "observed flux" values are useful in ionospheric physics and other terrestrial consequences of solar activity. ...
