QuickReduce, ODI-PPA, and odi-tools

QuickReduce is a set of pure python tools to reduce data from ODI. QuickReduce was created by Ralf Kotulla (UW Milwaukee, UW Madison) for the WIYN Observatory. The source code for QuickReduce is now on github. Documenation for the QuickReduce pipeline is available at this link.

The ODI-PPA is the online portal used to access, sort, and run QuickReduce on your ODI data. Information for gaining access and using the portal can be found at these help pages.

odi-tools is designed to work on images that have been processed using QuickReduce and downloaded from the ODI-PPA.

Running QuickReduce

After you become familiar with the layout and operation of the ODI-PPA, you can use these following steps to process your data. The options we list here are what we have determined to be the best practices for running QuickReduce. It is important to remember that these options can be data dependent. We will update these options should the change.

  • Add the images you wish to reduce to a collection in the ODI-PPA and from the collection action menu, choose QuickReduce. See the PPA help pages for information about creating collections.

  • Run QuickReduce with the following options. The [X] denotes that the option is selected.

    • [X] WCS
    • [X] Photometry
    • [X] Fringe (i- and z-band only)
    • [X] Persistency
    • [X] Nonlinearity
    • [X] Pupil Ghost (calibrations)
    • [ ] Pupil Ghost (science)
    • [X] Use Bad Pixel Masks
    • [X] Cosmic Ray Removal, 3 iteration(s)

  • You should give this job a meaningful name and check the Email me when when finished box.

  • When you receive the email letting you know your job is complete, download the QuickReduce data to your hard drive using the Download Results button on the QuickReduce job page. You don’t need to select any of the optional boxes, just name the job and click submit. Eventually a wget command will pop up. Copy it to your clipboard, navigate to the folder you want the data to go into, then paste the wget command in your command line.

  • At this point you are ready to start running odi-tools. See the Basic usage documentation for information on starting this process. See An Introduction to working with Quick Reduced Images for a brief tutorial on getting to know a QuickReduced image.
