Description CAL-The primary goal of the observation Abell 2690 is to accomplish and
aid the photometric calibration of OM in the B and V filter.
This comprises the definition of the zero point magnitude of the
natural system and the calculation of the coefficients of the
colour transformation. Secondary calibration item is the measurement of the
instrument PSF, which is accomplished by placing fast mode windows on two
field stars. The change of count rate with window size is the purpose of
introducing exposures with small image mode windows in the
V-filter and the magnifier. The change of PSF with window size can be
best studied with magnifier exposures. estimated OM overhead 7.4ksec.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
