Happy new Herschel year 2012 to all our Herschel colleagues!!


Herschel OT2 Phase 2 iterations on-going
========================================
Successful OT2 proposers are being contacted these days as part of the OT2 Phase 2 proposal submission exercise. The purpose of Phase 2 is to finalise the proposed observations to bring them to the status of committed observations, taking into account the HOTAC comments and the recommendations made by the technical reviewers to improve the observing strategies, and to avoid duplications with previously approved proposals and/or among successful OT2 proposals. This is to make sure that the helium is used in the most efficient way and to maximise the scientific return of the observations to be executed from now until the end of the mission.

As of today, a total of 306 (173 priority 1) PIs have been contacted out of a total of 373 (181 priority 1) programmes accepted. Don't worry if you are still to be contacted by the HSC regarding your proposal. Our goal is to finalise the process of contacting all OT2 successful proposers by 19 January 2012. We are extending the deadline for the users to provide their proposal updates until the end of January, in case this is required.

Herschel Data Processing Workshop 2012: Registration is now open!!
==================================================================
We are pleased to announce that registration is now open for the

"Herschel Data Processing Workshop 2012"

that will take place at ESAC on 20-24 February 2012.

The workshop will consist of an introduction to Herschel Data Processing for users with just a basic knowledge of HIPE (20 February 2012), followed by two blocks of sessions for more advanced users, addressing a variety of PACS DP issues (21-22 February 20120) and SPIRE/HIFI DP issues (23-24 February 2012). Each of these modules will be fine tuned to the wishes expressed at the moment of registration by the workshop participants.

We remind you that this workshop is primarily targeted to active HIPE users involved in OT1 programmes who want to get a deeper knowledge of the interactive processing of Herschel data in time for the analysis of the OT1 observations that they have in hand.

The workshop will include overview talks about the Herschel Interactive Processing Environment (HIPE) and on the status of the instrument pipelines, with demos and some hands-on sessions in which the participants will work on their own data with the in-person assistance of instrument experts.

For information about logistics, and registration instructions, you can visit the workshop website at:

http://herschel.esac.esa.int/DataProcessingWorkshop2012.shtml

Registration will close on: *Friday, 10 February 2012*


PACS Spectroscopy update: observing spectral lines in the 51-55 micron range
============================================================================
Noise performance investigations have recently revealed that continuum- and line sensitivities provided in HSpot v6.0 and earlier were too optimistic in the small wavelength range shortward of 55 micron, i.e. in the shortest edge of the PACS wavelength range. In HSpot v6.1.0 a correction factor of 2 at 55 micron and a factor of 3.5 at 52 and 50 micron have been introduced in spectral band B2A (blue channel, 2nd grating order, 51-73 micron range) so that correct sensitivity estimates are now provided.

Observations affected by this problem have temporarily been blocked for scheduling in the operational database and proposal PIs will be contacted in the following days and invited to update their AORs following the instructions which are provided in the latest version (v2.4) of the PACS Observers Manual (Section 6.1.3), available at:

http://herschel.esac.esa.int/Docs/PACS/html/ch06.html#sec-line-shortblue .

Calibration of Extended Emission with PACS and Comparison with IRAS/MIPS
========================================================================
For those of you interested in the topic of extended emission and comparisons to data from other missions (notably IRAS and Spitzer) we would like to point you to the following documents that have been on our website for a while. It should be noted that comparisons can be tricky since appropriate use of convolution kernels is required and corrections such as colour corrections can be large, particularly in the 70 micron PACS band. Please see the two documents for details.

"Comparative photometry of large galaxies with PACS, IRAS and MIPS/Spitzer":

"PACS 70 micron band extended emission comparisons with IRAS and MIPS/Spitzer"

Pointing Improvements
=====================
Especially within the last year, significant improvements have been made in the overall pointing accuracy of Herschel, mainly through improved understanding of the on-board star trackers following launch. Two updates last year brought the typical pointing error down from just over 2" to just over 1".

A summary description of Herschel pointing performance (current and past) can be found at:

http://herschel.esac.esa.int/twiki/bin/view/Public/SummaryPointing

Publications tracking - Do not forget to include the OBSIDs in your papers!
===========================================================================
A listing of refereed papers based on Herschel observations is maintained by the Herschel Project Scientist and made available through the HSC web site at:

http://herschel.esac.esa.int/ScientificPublications.shtml

If you have published a refereed paper based on Herschel data and you cannot find your publication in the list above, please let us know through the HSC Helpdesk.

We would like to take the opportunity to remind you that each publication based on Herschel observations should include the Target Name (if applicable), the Date(s) of the Observation(s) and the OBSID(s) to ensure that the data can be uniquely identified.

This will be of enormous help to us for establishing links from individual observations in the HSA to published papers, a service that we aim to provide in the future through the Herschel Science Archive.

Herschel-related conferences in the near future
