Citation text from the card

The source product page and sample header were checked on 2026-09-02.

SRON/ROG-GRON and the IRAS CPC team produced the data. LAMBDA, part of
HEASARC at NASA Goddard Space Flight Center, hosts this copy. The linked HEASARC
page is a data-use policy, not a separately named formal licence. It states:
“HEASARC materials are all available freely for your use.”

Every source header says `THIS TAPE CONTAINS CONFIDENTIAL DATA` and `PUBLICATIONS BEFORE DEC 1985 ARE RESTRICTED TO IRAS PROJECT SCIENTISTS`. The dated publication restriction has expired; LAMBDA now serves version 1.0 publicly and HEASARC states the current free-use terms on its data-use page.

Requested acknowledgement (exact text):

> We acknowledge the use of the Legacy Archive for Microwave Background Data Analysis (LAMBDA), part of the High Energy Astrophysics Science Archive Center (HEASARC). HEASARC/LAMBDA is a service of the Astrophysics Science Division at the NASA Goddard Space Flight Center.
