DIRBE Point Source Photometry Using Calibrated Individual Observations (CIO)

This interactive service permits browsing of the DIRBE data for investigations of bright point sources with well-known coordinates. (Click here for a more detailed description.) If you use this service in your research, please include the following acknowledgement in your paper: "This research used the DIRBE Point Source Photometry Research Tool, a service provided by the Legacy Archive for Microwave Background Data at NASA's Goddard Space Flight Center."

I. On-source position
Coordinate System:		Equinox:
RA. L or Ecl. L:		(e.g., 10h16m24s or 10.273)
DEC. B or Ecl. B:		(e.g., -25d19m34s or -25.33)
-or-
Object name:		(e.g., NGC 7538)

II. Choose a DIRBE Wavelength in microns (if choosing option 2,3 or 4):
*III. Choose ONE* Of The Following Four Options.**
(1) Source Visibility Plot Produces a 'visibility' chart that shows when the source was observed by DIRBE
(2) Source Photometry for One Day Produces a two-panel plot showing the available time strings passing through the source for a single day. The panels show the DIRBE scanning orientation on the sky and the scan photometry uncorrected for beam response. A table of the beam-corrected photometry is also produced.
1990 Day Number		(range: -20 to 264)
(3) Source Photometry trended over Many Days Produces a table of beam-corrected photometry over the requested DIRBE mission days. The results will be returned by E-mail (usually within 30 minutes).
Minimum 1990 Day Number		(range: -20 to 264)
Maximum 1990 Day Number		(range: -20 to 264)
Your E-mail address:		(e.g. user@college.edu)
(4) DIRBE Map centered on source position Display 4x4 degree DIRBE map (Zodiacal-light subtracted mission average data) in ecliptic coordinates at the specified wavelength centered on the source position
