Notes on SEDs from BRC34

• 213309.7+580345 - ick! drop!
• 213314.5+580351 - nice little one, check i2
• 213327.2+580413 - nice little one
• 213329.2+580250 - ogura 1 - nice one!
• 213334.0+580418 - strange. check in images, track down why no 2mass, very likely garbage.
• 213335.3+580647 - nice little one
• 213336.2+580324 - also pretty nice, if real - check i3i4 phot, check location in m24. limits would be good to add to the SED here at m24.
• 213337.3+580545 - icky, drop!
• 213338.6+580627 - icky, drop!
• 213340.8+580626 - pretty cute, check i2. check all irac bands?
• 213340.8+580631 - nice little one
• 213350.2+580326 - nice little one, though check i4.

NEW 9 NOV, LMR -- when going through this list, again and again, i noticed that the really big bright source in the heart of the BRC itself is not included on this list. Very peculiar. I got into the original source lists and discovered the following, not necessarily in this order, but close:

• The source is very bright at IRAC bands, saturated in the long frames. Very bright sources are often YSOs, so let's chase this one down.
• Source detection algorithms have a hard time with very bright sources, often finding false "clusters" of sources around a bright source, because of the complex shape of the PSF and/or saturation.
• The individual source lists done per channel indeed have this problem, and because they are not real, not all of the sources were correctly matched to the 'real' source.
• The 2mass frames are a good reference for the true position of the real source. The source does not appear in the J or H frames (more good evidence that it is a deeply embedded YSO!), but it does appear in K.
• I went and extracted the photometry from the 2MASS catalog, being careful to keep track of coordinates and limits.
• I went back to the IRAC source extractions. The source at this position in our catalogs has a successfully obtained i1i2i3 measurement, but no i4. The I4 measurement is somewhere else, too far away (more than 1 arcsec) for the computer to have matched it to this source.
• The MIPS source extractions have a larger coordinate uncertainty, and as such the MIPS-24 source here got incorrectly matched to a false nearby source.
• There is a MIPS-70 source here too! That also did not get matched properly.
• I went and redid the i4 aperture photometry at the correct location.
• I went and manually forced the M24 and M70 detections to match to the correct object.
• The new source is very likely a new YSO. It has a gorgeous SED. Optical spectroscopic followup will be next to impossible, given how faint it is in the NIR. Even NIR spectroscopic followup will be quite challenging. It's like 5 Jy at 70 um. Perhaps we can beg SOFIA time for him.
