PEARL Procedures is a suite of Igor Pro procedures developed for data acquisition and data processing at the PEARL beamline at the Swiss Light Source. PEARL Procedures requires Igor Pro 8 or newer.

Installation

PEARL Procedures should be installed according to the regular Igor Pro guidelines. Please read the Igor help About Igor Pro User Files for details.

Make a pearl-procs directory in your private or shared User Procedures folder, and copy the PEARL Procedures distribution there.
Create shortcuts of the pearl-arpes.ipf and pearl-menu.ipf files, and move them to the Igor Procedures folder next to your User Procedures folder.

Igor Pro 9 imports the HDF5 library by default. For earlier versions:

Find the HDF5.XOP (HDF5-64.xop for 64-bit) extension in the Igor Pro Folder under More Extensions/File Loaders (More Extensions (64-bit)/File Loaders), create a shortcut, and move the shortcut to the Igor Extensions folder next to your User Procedures folder.
Find the HDF5 Help.ihf next to HDF5.XOP, create a shortcut, and move the shortcut to the Igor Help Files folder next to your User Procedures folder.

PEARL Procedures are tested on Igor Pro 8.04, 64-bit. Please make sure to use the latest release version of Igor Pro.
