running IRSFRINGE

Running IRSFRINGE

1. Start the IRSFRINGE IDL tool by typing the following alias command (as defined in Downloading and Installing the Software) in the running directory:

irsfringe

2. Read in the IRS product, for example, "SPITZER_S3_5638912_17_1_E173247_tune.tbl", stored in the "data/" sub-directory.
Note that IRSFRINGE can only be used on the IRS products that come out of the extraction (post-BCD) pipeline, namely those with the filename suffix spect.tbl, spect2.tbl, or tune.tbl (see Archive Pipeline Products for IRS).

IDL> irs=ipac2irs('data/SPITZER_S3_5638912_17_1_E173247_tune.tbl')

3. Defringe spectrum of echelle order 18:

IDL> irsd=irsfringe(irs,order=18)

4. By default, IRSFRINGE removes both the main and second fringe components.
To remove only the main fringe component:

IDL> irsd=irsfringe(irs,order=18,/first)

5. To remove only the second fringe component:

IDL> irsd=irsfringe(irs,order=18,/second)

6. To run the same IRSFRINGE session and start the GUI:

IDL> irsd=irsfringe(irs,order=18,/GUI)

7. For all other options, see IDL documentation of IRSFRINGE
