Description:
WFPC2 and ACS images used to create the Heritage project color composite press releases. The data has been expertly prepared, significantly beyond the standard pipeline processing. This usually involves careful image registration, combination, and cleaning via drizzling, making it ready for further scientific analysis and educational use. These data will typically be made available at the time of the associated press release.
The Tübingen Echelle (TUES) obtained moderate dispersion observations (R=13,000) using an echelle grating including orders 40 - 61 from 910 - 1410 Angstroms. The instrument was designed and built by the University of Tübingen (PI: M. Grewing) and flew as one of three spectrographs on the ORFEUS/SPAS-2 mission for 14 days in November/December 1996. The instrumental resolution was about 10,000 and the effective aperture peaks at 1.3 cm2 near 1100 Angstroms. Objects were observed in a 10 arcsec entrance aperture. The wavelength calibration was established by means of interstellar molecular hydrogen lines.
