Background
__________
This is the second announcement of the conference "The Calibration
Legacy of the ISO Mission", which will be held at the Data Centre of
the Infrared Space Observatory (ISO) in Villafranca del Castillo near
Madrid (Spain) from the afternoon of February 5 to lunchtime February
9, 2001.
The scope of the conference - outlined below - reflects the wide range
of astronomical and instrumental calibration issues which have been
tackled during the history of the ISO project to-date. Particular
emphasis will be placed upon the relevance of the ISO experience to
calibration of future space missions, such as, for example, FIRST,
PLANCK, SIRTF or ASTRO-F. Contributions addressing the relevance for
the calibration of ground-based or airborne systems are also welcome.
The proceedings should gather, in one place, the legacy of the ISO
calibration work, with emphasis upon clear and thorough exposition of
the experience gained and of the lessons learned for the future.

Preliminary Programme
---------------------
It is envisaged that the meeting will be organised around the following
sessions :
Session 1: Inheritors of the Legacy - Future Missions and Systems
o A series of presentations addressing future space
astronomy missions and possibly other systems, and the
current planning for their calibration. With these
missions in mind, over the following days, we will assess
the ISO experience.
Session 2: Detector Physics
o All infrared detectors suffer from a range of physical
effects which complicate the characterisation of their
response to incident light. In the case of
photoconductors, as used for ISO, important effects
include (unstable) dark-current, sensitivity to ionising
radiation (see Session 3), baseline drifts and,
importantly, complex temporal variations in responsivity.
These modes of behaviour, and the latest methods under
study for modeling and correcting them, will be
addressed.
Session 3: Effects of the space environment, and the Spacecraft performance
o All spacecraft encounter varying degrees of disturbance,
or even hazard, from the space radiation environment.
We will discuss what we have learned about the properties
of this environment and its effects on instrumentation.
Other influences of the space environment to be addressed
include thermal loading and stability, the demands of
pointing and tracking, and the periods when the
spacecraft is in eclipse during which Solar illumination
and solar power are lost. These, of course bear strongly
upon the performance of the Spacecraft itself.
Session 4: Calibration sources and calibration source databases.
o This session will cover the challenges involved in
establishing databases of calibration sources, especially
those generated specifically to support the ISO mission
and now available to the whole community.
Session 5: Ground-based calibration - how relevant and important IS it ?
o Of course, all space-borne instruments need to be
rigourously tested for engineering integrity on the
ground before launch. Can these tests uncover all
problems which might affect in-orbit operations ?
How important is it to attempt to calibrate, rather
than simply to test, an instrument on the ground ?
How relevant is the ground-based calibration to the
behaviour in-flight ? If relevant - how essential ?
Could all calibration be done in-flight ??
Session 6: In-flight routine calibration.
o A range of fundamental calibration topics will be
addressed as they pertain to the ISO mission and
instruments.
Session 7: Cross-calibration.
o The consistency of the calibration of the ISO instruments
with each-other and with other systems, such as IRAS,
COBE, KAO, UKIRT etc... will be discussed.
Session 8: Data processing.
o This session will address important issues influencing
the scope and design of data reduction systems for
complex missions. Automatic "pipeline" type data
reduction and also more conventional Interactive Analysis
systems will be covered.
Session 9: Lessons Learned for future missions and wrap-up.
o Stressing the key theme of the conference, this session
aims to distill the essential conclusions and lessons
learned. These might help to anticipate problems and
difficulties in future missions, and help to eliminate
them. A substantial period will be set aside for an open
discussion.
