Abstract

Two successful sounding rocket flights were launched on May 15, 1997 and November 2, 1998 with an objective of providing inter-calibration with several of the instruments on board SoHO and TRACE. We will discuss here the results of the inter-calibration between the SwRI/LASP rocket imaging instruments and the Extreme-UV Imaging Telescope (EIT) on SoHO. The MXUVI sounding rocket instrument is a multi-layer mirror telescope equipped with a special internal occulter and light trap to provide full disk imags of Fe IX/X 17.1 nm and off-limb observations of He II 30.4 nm. The SoHO/EIT instrument is also a full disk multi-layer imager with four channels, Fe IX/X 17.1 nm, FE XII 19.5 nm, Fe XV 28.4 nm and He II 30.4 nm. By comparison with the EIT observations taken at the same time we can quantify the sensitivity degradation of the EIT detector, as well as measure the off-limb stray- light characteristics of the two instruments.
