4. A collection of images
... The TRACE images may be used without restrictions in publications of any kind. ... These two images, taken on 18 November 2000 at 15:54UT and 16:11UT, respectively, show such an event: the red circle in the image to the left shows a region where many loops are cooling, with bright loop tops (the intensity scales with the square root of the image to reduce the dynamic range). ... See also a collection of images related to the Sun, other cool stars, and solar-terrestrial effects . ... Images | ...

... These plots show spectra (either count rates or ux) and the background count rates. omgrismplotplot can be used to display a single spectrum or multiple spectra, produced by omgrism. The input FITS les must contain net count rates, background count rates and the associated errors. The spectra must follow a regular binning scheme (i.e. equispaced wavelength bins). omgrismplot allows the user to input the device type (e.g. Xwindow, Postscript, ...) for output. ... 7 Output Files 1. ...
