LAT Photon, Extended, and
Spacecraft Data Query


The Photon database currently holds 210818177 photons collected between 2008-08-04T15:43:37 and 2009-11-23T04:45:07 (239557417 and 280644307 seconds Mission Elapsed Time (MET)).

NOTE: For queries encompassing the whole sky (or close to it), please use the pre-generated Weekly Allsky Files.

    

NOTE: additional selections must be applied to data downloaded from the data server prior to use in a data analysis. See recommended data selections and LAT caveats for more details.

1. Do you want to search around a position ... ?


(e.g. '8 34 12, -45 45 00' or '128.55, -45.75' or 'Vela')
degrees

... and/or search by date?



If you do not enter anything, it will return results from the past 6 months.
For Gregorian dates, please enter in the format YYYY-MM-DD HH:MM:SS, with the start and (optional) end time separated by commas.
Enter the start and (optional) end MJD in the form MMMMM.mmmmm,MMMMM.mmmm
For MET (Mission Elapsed Time), enter any integer values >= 0, separated by commas.
If you would like to search from the beginning of the mission, put in START instead of a start value.
If you would like to search up until the most recent point, put in END instead of an end value.

... and/or search by energy?

MeV
Enter the minimum and (optional) maximum energy, separated by a comma.
(By default, only data between 100 MeV and 300 GeV is returned.)


2. What missions and catalogs do you want to search?
