X-ray astronomy program at CIT

The X-ray astronomy program includes a rocket-borne Wolter type 1 telescope with associated position sensitive detectors, ground based observations in the optical and infrared spectral bands, an experiment on the HEAO-A spacecraft, and a rocket-borne test flight of the HEAO-A. A modified detector was used to study Cyg X-1 millisecond pulse structure and spectra.
