Reduced Data in 4,16,64 Sec Integrations, Attitude, Absolute Time and Background


Availability: Data Available from Experimenter


This data set is held by the experimenter. It consists of both original and reduced data stored on one-half inch, digital magnetic tape produced on a NOVA 3 computer system. Reduced data are stored on total counts detected in 4-, 16-, or 64-s integrations, on and off the source being observed. Summed counts detected in the total observation period of low background data (approximately 2000-s exposure time) are available for spectral fits. Attitude and absolute time are included for the data. This data set can be accessed by using the computer reduction facilities at HCO/SAO. Further information or access can be obtained through NSSDC or by contacting: Prof. Jonathan E. Grindlay, Harvard College Observatory, 60 Garden Street, Cambridge, MA 02138. For an observing catalog of X-ray sources observed by this experiment, the total experiment, and the total exposure time on each source, see data set NSSDC ID 74-070A-03B.
