Cost Review - The Delta CR Report is in and the NA Cost/Management Review is over. Risk Register
ASAC Meeting - The ASAC has met. Among their charges: Review the existing analysis fo the polarization and mosaicing performance of the hybrid ALMA array and consider the priority and timescale for further analysis by the Science IPT. We submitted an estimate of resources needed to the Board.
Science Requirements -- The revised document is located in the Science area.
Characterization -- de Breuck is new APEX PS and may be able to help.
Talk on Science IPT Given to ASAC and handed to N.American cost/management review.
NAWG tomorrow. Links to Jan 2006 URSI talks: Session J3 Room 265 Friday Jan 6 1320 Challenges and New Algorithms for Interferometric Imaging Organizer: S. Myers
Submillimeter Frequency Protection. The radio astronomy spectrum management community continues to work toward the possibility of extending the frequency allocation tables above 275 GHz. The goal is to create new spectrum allocations for the radio astronomy service that will protect spectral lines of interest to us, up through frequencies as high as 3 THz. We are working within the International Telecommunication Union to facilitate the discussion of extending the allocation tables. The topic is on the agenda for the 2010 World Radiocommunication Conference (WRC-10). Because those of us who are addressing this issue at the ITU are not submillimeter observers, we are in need of feedback regarding the specific bands of interest. At this time, there is a single document circulating within Working Party 7D (Radio Astronomy) of Study Group 7 (Science Services) of the ITU which contains a list of spectral lines of interest to the radio astronomy service above 275 GHz. The list is in two parts: lines between 275 - 1,000 GHz, which is based upon a list established by the IAU (Table 3.1 of the attached document); and lines of interest between 1,000 - 3,000 GHz, which is mostly based upon line data obtained from the National Institutes of Standards and Technology (Table 3.2). At this time, the second list is in need of close scrutiny by the submm community.
We would be most appreciative if you were able to take a look at Table 3.2 of the attached ITU document and provide corrections, omissions, or improvements to the lines listed there. Note that the list of spectral lines of interest does not take into account atmospheric windows, since any new allocations may include space-based use of these bands.
We would also be most appreciative if you could suggest other submm astronomers who might also be able to provide feedback. Please feel free to circulate the document to colleagues who may be able to provide input, but please ask them to communicate to me any such feedback they may have.
