Homework:

a. Process the data
Use raw data in /d/crow1/edges/data/opt/wiro/raw/may27282014/
The logfile is called log.txt
 "Process" the ugr data for "NGC4220" to OTZF stage
 Read IRAF manuals at iraf.net 
  IRAF Docs->CCD Reductions-->A User's Guide to CCD Reductions w/IRAF

b. Align and stack 
Carry out photometry on five unsaturated stars in the field of "NGC4220" for g band.  You may use my script I generated for "photing", aligning, and stacking the RBO data:
/d/crow1/edges/data/opt/rbo/proc/may28292014/proc.doc
