Description | In order to verify the absolute timing there is the opportunity to contemporaneously observe the Crab with Chandra and in the optical using an MPE developed fast photometer to get a radio-ephemeris independent phase solution between the optical and X-ray pulses. The optical (and Chandra) observation are scheduled for virgul September 26. Since the accuracy of determining the pulse period is correlated with the total range of the observation we propose to perform 2 observations of 10 ks in up to three consecutive orbits, in order to have a long time base line. For the pn the electronic chopper might be required in order to avoid counting mode. This will be arranged via OCR if needed. Obs. greater equal 04 are routine cal. 3x5 ks in single orbit. |

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. |
