This Explanatory Supplement accompanies the IRAS Sky Survey Atlas (ISSA) and the ISSA Reject Set. The first ISSA release in 1991 covers completely the high ecliptic latitude sky, || > 50°, with some coverage down to || > 40°. The second ISSA release in 1992 covers ecliptic latitudes of 50°>|| > 20°, with some coverage down to || > 13°. The remaining fields covering latitudes within 20° of the ecliptic plane are of reduced quality compared to the rest of the ISSA fields and therefore are released as a separate IPAC product, the ISSA Reject Set. The reduced quality is due to contamination by zodiacal emission residuals. Special care should be taken when using the ISSA Reject images (§IV.F).
In addition to information on the ISSA images, some information is provided in this Explanatory Supplement on the IRAS Zodiacal History File (ZOHF), Version 3.0, which was described in the December 1988 release memo (Appendix H).
The data described in this Supplement are available on permanent media from the National Space Science Data Center (NSSDC) at the Goddard Space Flight Center. The interested reader is referred to the NSSDC for access to theIRAS Sky Survey Atlas (ISSA).
