It has come to our attention that some possibly important
changes have been released in a revision to the PACS
Observer's Manual. These changes are specifically related
to the PACS spectroscopy modes.
The areas of the manual changed can be found at the URL
http://herschel.esac.esa.int/Docs/PACS/html/ch08.html.
It affects SED mode
and Wavelength-switching modes of the PACS Spectrometer.
We encourage proposers to the current Key Programme AO to
acquire the revised document from the ESA HSC web site.

TEXT OF ANNOUNCEMENT FOLLOWS:
On 17 October 2007 an update to the PACS Observers' Manual Section 4.2,
PACS spectrometer AOTs (POMv1.5) was posted:
http://herschel.esac.esa.int/Docs/PACS/html/ch04s02.html
It imposes a minimum repetition factor of 2 in the following line and
range spectroscopy AOTs: SED mode, range scan with Nyquist sampling, and
line spectroscopy in "bright line" chopping/nodding.
It also restricts the use of line spectroscopy with wavelength
switching to the
mapping pointing mode only, with a minimum raster size of 2 by 2.
NOTE: Not using the above modes?? Then STOP reading right here!
Because the AO deadline is close, YOU ARE NOT REQUIRED TO ADAPT YOUR
PROPOSAL to incorporate the above update, however, you are allowed to
do so.
YOU ARE REQUIRED to tell the HSC Helpdesk WHETHER OR NOT you have
adapted your proposal based on the new information.
Case 1: "I HAVE ADAPTED my proposal". You need say no more.
Case 2: "I HAVE NOT ADAPTED MY PROPOSAL". In this case let us know your
preference:
- would you like to ask for additional observing time
- would you prefer to cut down on the number of observations
- would you prefer to make other changes to the proposal?
YOU SHOULD PROVIDE THIS INFORMATION TO THE HSC HELPDESK BY 30
OCTOBER 2007 AT UT 12:00 HOURS, by raising a ticket with the title
"POMv1.5 statement concerning proposal ".
... and we will work with you in the post-deadline period to
adjust your proposal as needed.

Please note: Please do not send this important email to the NHSC
helpdesk. Rather click on the link above to take you to the European
Helpdesk which is where you must submit this message if you are
affected by the announcement.
