... Observers may find that they wish to perform parts of the pipeline reduction again on their data using these tasks. Typical examples will be to re-perform cosmic ray rejection, altering the input parameters or using data from separate datasets, or to perform one-dimensional spectral extraction on long-slit data or to modify the input parameters (e.g., aperture extraction box, or background region) when doing one-dimensional spectral extraction for echelle data. ... Rectify spectral images. ...

Next: TAP 26 Up: Results Previous: Results . While the bulk of these stars were located in the Orion OB1a and OB1b fields, two stars of particular interest were monitored from our Mount Stony Brook Observatory. One of these stars was TAP 26 (NTTS 041559+1716, HBC 376). This star, located in Taurus, had a measured rotational period which was inconsistent with its . The other star was P1724, located near Orion OB1d, for which x--ray periodicity had been observed. TAP 26 . P1724 . ...

... Finally, the individual observations themselves are reduced, using the parameters from the extinction solution. ... That is, the extinction solution can in principle produce results if we observe extinction star 1 only in passband A and star 2 in passband B on night 1, and star 1 only in passband B and star 2 in passband A on night 2. ... Even if the passbands are linked by color terms in the extinction, the solution is possible, because we do obtain mean colors for each star. ...

spaceweb@oulu.fi - last update: 20 September 1998, 2020 UT (RR) . Traveling Convection Vortex (TCV) is a name given to a specific type of daytime magnetic impulsive events observed by high-latitude ground-based magnetometer arrays. Since the most likely source for TCVs is the solar wind , they are considered to be important processes in transfering energy from the solar wind into the magnetosphere . ... For example, one AMPTE Lithium release in the solar wind caused a TCV event . ...

... In this activity, students will observe that the faintest stars which they can see in the sky are affected by many things: the adaptation of their eyes to the dark, the presence of clouds or haze, the time of year, and the presence of light pollution. General Information . ... After completing this activity, students should have a better understanding of the practical processes for dealing with the light pollution problem and with other environmental and societal issues. << previous page | ...

... The improvement will be more pronounced in our crowded Wide Field Camera (WFC) images, and may be increased further through use of a more sophisticated method of combining the individual dithered images. Our analysis allows us to check for point spread function shape variations in the HST Planetary Camera (PC) field. ... In crowded field images, we are deriving information about the faint end of the luminosity function (LF) from the texture of the image background. ...
