E-MAIL: Sharon L. Connolly, sconnolly@mail.arc.nasa.gov. THIS NOTICE CONSTITUTES AMENDMENT NO. 1 TO THE COMBINED SYNOPSIS/RFQ FOR CCD DETECTOR. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to provide additional information to all interested quoters as a result of a question submitted: Question: Is a 15 micron pixel size acceptable? Answer: A pixel size of 15 microns is not acceptable. Smaller pixels are required because the size of the pixel compared to the focal length of the telescope, to be used for the Government's application, sets the angular size of the sky that is viewed by each pixel. A pixel size of 9 microns is necessary to achieve the photometric precision required for this procurement. The due date for receipt of offers is not extended. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on June 11, 1998. Documents related to this procurement are available over the Internet and are in Microsoft Office Suite (Word 6.0, Excel 5.0, or PowerPoint 4.0) format and reside on the World Wide Web (WWW) server which may be accessed using a WWW browser application.
