Data Reduction

IDL is the recommended data-reduction package for Arecibo spectral-line data.

Data Formats

The different back-ends produce different data format. Information on the header information can be found in the following places:

Where's My Data?

Note that these directories contain a very large number of files, you are strongly recommended to use ‘ls *⟨projid⟩*’ to find your files.

  • Mock spectrometer data should be in /share/pdataN/pdev/ (where N = 1 - 14)

  • WAPP spectral line data should be in /share/wappdata/

  • Interim Correlator data should be in /share/olcor/ or /proj/⟨projid⟩

Converting Interim Correlator Data

To 'standard' FITS format

To SDFITS or CLASS data formats

Legacy Data Reduction Packages

These packages are not actively supported and may no longer work.

  • Analyz: Native Arecibo format for older data..

  • AIPS++: Interim Correlator data converted into SDFITS can be reduced with the AIPS++ package.
