10 May 2004 Dale, Finn ----------------------------------------------------------------- Wyoming update -------------- -Filter wheel fabrication -New hire: observing assistant Christine Lamanna -New grad student: Travis Laurance his tentative summer duties: -observe/reduce -filter profiles -learn and simulate with SExtractor -create/maintain group webpages for better communication/organization -REU student: Rebecca Harbison -Observing plan UMASS update -------------- -Dec 2003 "run" -June 2004 run: 2nd half of June 1 for 16h 36m field -Anything else? For discussion -------------- -NOAO proposal? "survey" proposal is perhaps a good option: up to 5 years. Next deadline likely Sep 2004. A Survey Program is a significant observational program which: * addresses novel, well-focused scientific goals; * enables scientific programs requiring large, statistically complete, and homogeneous data; * provides a basis for planning more detailed follow-up studies; * enables extensive archival research; and * represents a significant enhancement over existing surveys. Questions -------------- -What redshift will you exactly cover at MMT? What other filters are available? -Which exact coordinates for the 16h 36m field? -Overlap stragegy? -1 solar mass/year strategy? -Copy of proposal? -Timeline for finishing? -I have preliminarily selected z=0.61 (1.063um) over z=0.71 (1.125um) since z=0.61 provides better "z-spacing" for the 6 epochs (and there is a dip in transparency at 1.125um). But how in the heck can I continuum subtract? e.g. the 2MASS J-band filter runs from 1.11-1.40um (50% FWHM). http://www.ipac.caltech.edu/2mass/releases/allsky/doc/figures/seciii1bf3.gif The Gunn z filter is not a good alternative: http://voservices.net/filter/filterdtls.aspx?filterid=18 -Travel to Wyoming or Arizona a good idea? e.g. colloquium --------------------------------------------------- Telecon notes/Follow-up to telecon --------------------------------------------------- Finn says Janice Lee, Kennicutt's soon-to-be-graduating grad, is interested. Have Dupczak scan DSS fields for potentially-harmful bright foreground stars. Report results to Finn. MMT NIR camera FOV: 3.1' (circular). Finn is going down to 0.3 solar masses/year for her cluster work (assuming Av=1). This is like 2 hours integration, or half a night w/overhead. She could probably crank out several of these fields if she just goes down to 1 solar mass/year. Finn's filter is centered at 1.209um (z=0.84). She reiterated her interest in carrying out a complete 0.5 sq deg survey at this epoch, even though it would take many nights! :) The same camera on the Steward 90" (2.3 m) yields 8.5' FOV (circular). Perhaps Lee would be interested. Because J band does not go down to my proposed z=0.61 (1.063um) wavelengths, maybe I should purchase my own broadband filter for continuum subtraction purposes. For calibration, Finn is using 2MASS stars in the field. She uses the JHKs fluxes and a stellar model to infer the narrowbad fluxes.
