	ADDENDUM to the ROSAT Status Report #164 of 16 APR 98

The RSDC at SAO has provided the following clarification
of the announcement on the "Spectral Calibration of the ROSAT HRI".

The spectral analysis project described in the ROSAT Status Report
#164 was carried out under the auspices of an ADP grant with
A. Prestwich, PI (the previous announcement erroneously implied that
it was a product of the SAO RSDC).

We also want to emphasize that this project is on-going.  A critical
assessment of the effectiveness of the spectral analysis and an
evaluation based on its application to several celestial sources have
yet to be done.  Attempts to derive quantitative spectral results from
HRI data must entail careful analysis on the part of individual
investigators.
