• ptolemy.rc / gconfig
• comparison with IPP config
• photcode file

• DVO extra functions
• relphot
• uniphot

DVO Elixir Configuration

• We always need a way to define parameters
• site-specific parameters eg, locations of data
• camera-specific parameters pixel scale, layout
• analysis-specific parameters statistics
  box-size, etc
• a hierarchical approach is important
• on-the-fly modifications are convenient
• /.ptolemyrc or ptolemy.rc

DVO Elixir Configuration

• gconfig read / interpret configuration data
• gconfig dump complete config files
• gconfig (KEYNAME) return parsed key value
• gconfig -D KEYNAME VALUE (KEYNAME)

IPP Configuration

• similar structure, with additions
• /.ipprc
• uses psMetadataConfig format
• includes type information and in-line comments

Example .ipprc file PATH STR

Database configuration DBSERVER STR

psDBInit) DBUSER STR ipp
