Welcome to INTEGRAL Gamma-ray Data Tools Documentation!¶
The Integral Gamma-ray Data Tools (GDT) is a toolkit for INTEGRAL data built on the GDT Core Package.
The INTEGRAL satellite was launched on October 17, 2002 by a Russian PROTON launcher from Baikonur in Kazakstan. It has a highly eccentric orbit with a revolution period around the Earth of 3 sidereal days (slightly less than 72 hours). INTEGRAL was designed for a nominal lifetime of 5 years. In October 2009 it was decided to extend the mission at least up to the end of 2012. As of June 2023, INTEGRAL continues to operate despite the loss of its thrusters through the use of its reaction wheels and solar radiation pressure. It consists of four main scientific instruments:
1. The gamma-ray spectrometer SPI (20 keV - 8 MeV): The Spectrometer on INTEGRAL (SPI) measure the energy of gamma-rays with an extraordinary accuracy over an energy range between 20 keV and 8 MeV.
2. The gamma-ray imager IBIS (15 keV - 10 MeV): The Imager on Board the INTEGRAL Satellite (IBIS) has been optimised for fine imaging and precise detection of radiation sources. IBIS achieves an angular resolution of 12 arcmin over an energy range between 15 keV and 1 MeV (electron-volt).
3. The two X-ray monitors JEM-X (3-35 keV): Coded aperature mask with 2 high pressure microstrip gas chambers. FOV 4.8°, detector area each 500 \({\rm cm}^2\), spatial resolution 3´.
4. The optical monitoring camera OMC (500-850 nm): The OMC is a CCD detector of 1024 x 1024 pixels located in the focal plane of a 50 mm lens with a V (visible) filter. The total field of view of the OMC camera is of 5 x 5 degrees.
