9. Where is the BRC? What is a point source? What is the BRC? What is a foreground star?
 
 
 
10. Under Previously identified sources, checking the duplicates.
 
 
 
11. What is photometry? What is it measured in? What do we convert it into?
 
 
 
12. What does APT really do for you?
 
 
 
13. Why does the MOPEX source pick up wrong objects and miss others?
 
 
 
14. Working with the data tables: Save files in a standard format
 
*a. BRC number
 
*b. Cand or known
 
*c. Underscore
 
*d. Initials
 
*e. underscore
 
*f. Two-number date
 
*g. Three letter month code
 
*h. Example: 27cand_chj_09jul.xls
 
 
 
15. Data tables:
 
 
 
*a. Make SEDS with the all 38 candidate objects.
 
 
 
16. Color-color diagram
 
 
 
17. Color-magnitude diagram
 
 
 
Long-term goals:
 
 
 
1. “Pretty pictures” for poster. Three-color images of BRC-27 and BRC-34.
 
 
 
2. Science poster
 
 
 
3. Education poster

=Extra notes:=
 
 
 
Powerpoint 1:
 
 
 
NASA has some great observatories.
 
 
 
Why do we need to use different telescopes?
 
 
 
1. “To see different things”
 
*a. X-rays vs. gamma rays
 
*b. Atmosphere absorbs certain wavelengths
 
*c. Atmosphere is opaque to certain wavelengths
 
*d. Dusty regions are not seen in optical, can’t see through it
 
 
 
2. Why are we using archival data?
 
 
 
*a. Data does need to be sorted but by the computers but
 
*b. Cryogen is gone.
 
*c. Surpassed its lifetime.
 
*d. 3 & 4 and MIPS is gone but lots of data just haven’t been looked at
 
*e. Hotter objects shorter waves
 
 
 
Powerpoint 2:
 
 
 
1. What is SSC?
 
 
 
*a. Spitzer Science Center
 
 
 
2. Wavelengths and bands
 
*a. Bands are x number across but numbers correspond to center
 
 
 
3. Using heritage data
 
 
 
4. Hopefully use WISE data
 
 
 
5. Good to look through the rest of packet
 
 
 
6. P. 34 jail bars and instrument artifacts. Washed out some of the things around it. Messy.
 
 
 
*a. If we found this, we could smooth it out not scientific information
 
 
 
7. Chemistry and elements used
 
 
 
Powerpoint 3:
 
 
 
1. Star formation. Major topic on top of page 3. 
 
*a. Small stars and stars with dusty disk
 
*b. Phase 0 yee hah yakky yak
 
*c. Probably won’t be able to pin down the age of the object but will not be able to pin down the distance.
 
*d. Links and files to movies
 
 
 
2. Extrasolar planets are hot topic
 
*a. Iphone app to let you know when new planets are found
 
 
 
PowerPoint 4:
 
 
 
1. Most important. Goals:
 
*a. Science poster
 
**i. Paper written
 
*b. Education poster:
 
**i. How can we bring this to other students?
 
**ii. How has it opened new doors for you?
 
**iii. STEM careers
 
**iv. Writing
 
*c. Other teams will have at least 2 posters
 
 
 
2. Classes on pg. 7 and how it relates to SEDs
 
*a. How is the energy distributed over different wavelengths
 
 
 
3. Blackbodies
 
*a. Perfect radiators
 
*b. Give off all the energy that they produce
 
 
 
4. SEDs
 
*a. Slopes: left and right
 
 
 
5. Color-color diagrams p. 15
 
*a. Magnitudes
 
*b. Reddening of the object
 
 
 
6. Photometry
 
*a. Not using the MOPEX program
