- 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 (done)
- get up to Numpy and Scipy in Python
- bug Chris about PanStarrs data file locations on Odyssey machine (done)
- extract multicolor light curves for ~10,000 objects, in g,r,i,z,y.
- make plots of colors (g-r) vs. (z-y), etc. and reject outliers from the stellar locus (see High et al SLR paper)
- Do this for different pairs of data, taken at different times.
...
- I can process data and produce plots now. Here are some light curves:
Thursday, 20 June
- Finished reading "Learning Unix for OS X Mountain Lion"
- Gautham informed me that there's a hard disk error on the server. As a result file operations (such as cp) are not completing. This is giving me considerable trouble trying to process the data. I'm waiting for the disk to get online again.

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