Dear AKARI Open Time FIS users,

The AKARI FIS team has released the result of careful analysis of the
FIS in-orbit performance. The details are available at:

In summary, the SW bands (N60, WIDE-S) are confirmed to be as
sensitive as predicted before launch (i.e. as documented in the
Observer's manual).

However, for the LW bands (N160, WIDE-L), various factors have brought
the sensitivity to a level a factor of four (0.5 sec integration) to
eight (2 sec integration) worse with respect to the pre-launch values
published in the Observers Manual.

Due to the difficulty of major revisions to the observing programme
given the increasing operational constraints, we would like first to
assess the impact of these new performance numbers, with the aim of
maximizing the scientific return of the mission.

We kindly ask you to check if the science goals of your proposal are
maintained for your target list, given the good performance of the
FIS-SW bands and of the IRC bands.

Please let us know the confirmation of the present observation plan
or if you would like to change the obsevation parameters.

We would appreciate your prompt response,


Sincerely yours,
AKARI Helpdesk
