| Abstract: |
The NASA/IPAC Infrared Science Archive (IRSA) curates both data and
analysis tools from NASA's infrared missions. As part of our primary
goal, we provide long term access to mission-specific software
from projects such as IRAS and Spitzer. We will review the efforts by
IRSA (and within the greater IPAC before that) to keep the IRAS and
Spitzer software tools current and available. Data analysis tools
are a vital part of the Spitzer Heritage Archive. The IRAS tools
HIRES and SCANPI have been in continual use since the 1980's. Scanpi
offers a factor of 2 to 5 gain in sensitivity over the IRAS Point
Source Catalog by performing 1D scan averaging of raw survey data at
specified arbitrary position. In 2007 SCANPI was completely
modernized, with major code revisions. HIRES returns IRAS survey
images with higher resolution than the IRAS Sky Survey Atlas
(ISSA). We are currently undertaking a modest revision to the tool
to ensure continued reliability. In the next two years, the US
Planck Data Center plans to adapt both tools for use with Planck
data, and deliver them to IRSA for long term curation. |
