GBTIDL is an interactive package for reduction and analysis of spectral line
data taken with the Robert C. Byrd Green Bank
Telescope (GBT). The package consists of a set of straightforward yet
flexible calibration, averaging, and analysis procedures (the "GUIDE layer")
modeled after the UniPOPS and CLASS data reduction philosophies, a
customized plotter with many built-in visualization features, and
Data I/O and toolbox functionality that can be used for more advanced tasks.
GBTIDL makes use of data
structures which can also be used to store intermediate results.
- The package consumes and produces data in GBT SDFITS
format. Observers after May 31, 2005 have uncalibrated SDFITS data
available to them at the end of a run; observers prior to this date must
create their own SDFITS offline prior to analysis.
- GBTIDL can be run online, and have access to the most recent
data coming off the telescope, or can be run offline on preprocessed SDFITS
- What if I don't have an IDL license? If you cannot download
and use the package directly from your home institution, you can use one
of NRAO's licenses by logging into your GB account, or by reserving the
dedicated IDL machine in Charlottesville.
- Can I use GBTIDL on my data from a single-dish telescope other than the GBT?
With some extra work, yes. Please see the
for a description and outline of that work.
