When the planning stage is complete, the architect will have a blueprint of the house, the CDF designer will have a skeleton table.
Before the (CDF) building stage can begin, a designer must have a machine-readable data set ready to put into the form of a CDF data set. The building stage involves writing the Fortran or C code which is discussed in detail in the CDF User's Guide or C and Fortran Reference Manuals which can be downloaded from this site. (or see the CDF home page.) This step can be skipped by using the program makeCDF.
When the data is put into the CDF (running the computer program), the CDF data set is complete and can be viewed as a list of numbers (e.g., using CDFlist), transferred to another location, manipulated, or visualized via plotting software (e.g., using CDAWeb).
Usually one CDF data set is created for each ISTP/IACG instrument. The files associated with each CDF data set are produced daily.
