Rob,

As you know, we have been working quite a bit these past two weeks on
2nd Look target selection.  Cannon and Bendo were kind enough to suggest 
some candidates, and I'm happy to say that Moire proved to be invaluable.  
She really helped us pull things together.  Of course the whole SINGS IRS
group led the way.

Moire and I have been maintaining web pages to keep track of all the
information.  Below I provide a summary, but I encourage you to go over 
some of this online information/plots/images/etc with JD.

http://physics.uwyo.edu/~ddale/research/sirtf/2ndLookRound2/2ndLookRound2.html
(sings/sirtf)

In particular, near the bottom of my website I provide a link to a
"Working database+comments of 2nd Look targets".  This file includes all
of our preliminary candidates with coordinates, fluxes, rankings, comments,
peak 24um surface brightness, etc.  

In addition, I have provided below that a link to a simplified version of this 
file, after having culled out any candidates that I did not rank a 0, 1, or a 2.  
There are 44 of these "high priority" candidates.
Rank 0: A Prescott-based selection which helps to fill out 8/24 and 8/Ha space.
        Moire's plots show both what we've already covered in this parameter
        space (big circles), and what we propose to cover (big squares).
        Requires a minimum Inu24 of 3 MJy/sr averaged over a 12" diameter region.
Rank 1: Usually a follow-up to something we just missed previously.
        Requires a minimum peak Inu24 of 5 MJy/sr
Rank 2: Interesting based on morphology, IR/optical, line/continuum, etc.
        Requires a minimum peak Inu24 of 5 MJy/sr

Recall that we still nominally have 31 TBD extranucs, and that we propose to 
drop Low+High res nuclear maps for six faint targets.  Moreover, we propose to 
convert one of these dropped targets into an extranuclear map at a new position.  

I'm not assuming we'll do everything we propose.  But if we did, the total
SINGS time budget would be near 512 hours (see below).  Please let me know 
what you and the larger team suggest, and I'll get crackin' on AORs.

Cheers,
Danny

Summary:
--------
-PID 159:     405.4 hr
-PID 193:      95.3 hr
-PID 150+193: 500.7 hr  (including 8 recently-submitted SL sky AORs and 39 optically-selected + 2ndLookRound1 extranuclear targets)

-PID 159 after dropping six Low+High Res maps: 393.7 hr
-PID 193 after dropping all TBD extranucs:      56.6 hr
-PID 159+193 total after these drops:          450.3 hr

-We offer up 47 extranuclear candidates, including 
  - 29 sources selected from Moire's analysis, that nicely fill parameter space
  -  6 to redo N2403 extranucs
  -  1 converted nuclear->extranuclear map (IC 2574)
  -  1 to catch missed bright spot in Tololo 89
  -  1 to catch missed bright spot in NGC 5408
  -  9 regions deemed interesting based on morphology, IR/optical, line/continuum, etc
-These 47 candidates would require 56.4 hr, including clustering efficiencies

-We offer up two LL strip-map-fattening candidates
  - based on interesting line/continuum ratios in (incompletely-mapped) ring regions
    of N1566 + N4736
  - we would double the LL map widths
  - we have or propose extranuc maps to catch these regions in HighRes + SL
-These two AORs would require 2.1 hr, including clustering efficiencies

-We propose to obtain 11 minute SL sky observations for each extranuc map (except
 for the one in N5408 where the SL outriggers will suffice)
-This would cost us 3.2 hr
