1.2.3.1 Dust Trail Images:
Russell Walker searched the IRAS Sky Survey Archive Reject Set and found 54
images that contained the dust trail of comet 9P/Tempel 1. The Reject Set are
images taken within 20° of the ecliptic plane and are of reduced quality compared
to the rest of the Survey data due to contamination by zodiacal emission residuals
and the zodiacal dust bands.
For future reference, the FITS trail images were converted to JPEG images and
saved in the Documentation area of this archive.
1.3 Error Handling and Data Quality Assessment
It is inevitable that errors will be introduced into the archive even with data validation
procedures applied to the volumes. A plan is required to handle errors discovered in data
volumes that have already been produced.
As errors are discovered, they are reported to user community. An ERRATA report file is
maintained to track and document all discovered errors. At the conclusion of the
production of the NC volume set, a final CD-ROM is prepared that contains corrected
files for all discovered errors.
