Li Kewei

For Kewei to do

• Read the rest of the book! (done)
• Get swipe card access to the lab (done)
• Start to learn about scripting and shell scripts (bash) in Unix of Mac
• get up to Numpy and Scipy in Python
• bug Chris about PanStarrs data file locations on Odyssey machine (done)

For Chris to do:

1. tell Peter to move the computer that's in the office (tomorrow, Thursday)
2. approve RC account  (done!)

Data access on Odyssey:

1. Run JAuth.jar to get login key
2. ssh -Y into to odyssey.fas.harvard.edu, or herophysics.fas.harvard.edu, using the electronic key. 
3. run tcsh
4. source .myrcstubbs
5. data are at /n/panlfs/data/MIRROR/ps1-md/gpc1/
6. nightly science uses individually warped images, nightly stacks run on stacked frames
7. image types: wrp is warped. 
8. see available modules with "module avail"
9. load a module with "module load hpc/ds9-5.6"
10. photometry is in .cmf files, as FITS tables. 
11. in python: 
    1. import pyfits as p
    2. p.open('filename')
    3. print a[0].header
12. or, imhead on command line
13. a[1].data.AP_MAG for aperture magnitudes
14. PSF_RA and PSF_DEC are in the skycell files. 
15. make a scratch directory for data in /n/panlfs

Photpipe photometry as text files are at

run gpc1v3 to invoke scripts for photpipe

then files by ut, but aubsets a-j as 10 spatial subsets. 

for example

/n/panlfs/data/v10.0/GPC1v3/workspace/ut130525f/41

and use the dcmp files, four per stacked image. 

take catalog photometry entries and add ZPTMAG to all entries to get corrected photometry. 

photpipe are DoPhot with aperture correction.
