75" LWS Pointing Overlays on DSS and Link to 1x1 degree IRAS Images
This observation has been reduced by the following steps:
- Estimate and remove dark current using LWS Interactive Analysis (LIA).
- Derive the Absolute Responsivity Correction (ARC) factors using LIA. The ARCs are derived from internal calibration flashes and scale the detector responsivities to the values measured during the LWS calibration.
- Remove outlying points by hand using ISAP. These points are typically caused by cosmic ray hits.
- Average the data across scans and scan directions using a 3-sigma "special clip" algorithm designed for LWS data found in ISAP.
- Write out to FITS and ASCII files.
Calibration Notes:
- The continuum flux may not be well determined, especially for weak sources. See the LWS Handbook and calibration notes for more information.
- For extended sources, NO EXTENDED SOURCE CORRECTION has been applied. See the LWS Handbook and calibration notes for more information.
