The NRL OSO-4 Bragg crystal spectrometer instrument [PDF]
Two Bragg crystal spectrometers were placed on the OSO-4 satellite to study solar flare plasmas by their spectral emissions. The solar flare plasma parameters were measured with these spectrometers, which together covered a total wavelength range of 0.6 ...

A search for X-ray polarization in cosmic X-ray sources [PDF]
Fifteen strong X-ray sources were observed by the X-ray polarimeters on board the OSO-8 satellite from 1975 to 1978. The final results of this search for X-ray polarization in cosmic sources are presented in the form of upper limits for the ten sources ...

Continuing data analysis of the AS/E grazing incidence X-ray telescope experiment on the OSO-4 satellite [PDF]
The work to correct and extend the calculation of the theoretical solar X-ray spectrum produced during earlier OSO-4 data analysis is reported along with the work to formulate models of active regions, and compare these models with the experimental ...

The 78.4 day period of Cygnus XR-1 [PDF]
A search for a 78.4 day modulation in the high energy X-ray flux observed with OSO-8 and in the U-band optical polarization is reported. It is suggested that if such a modulation does exist, it is more likely to be related to the rotation of the free ...
