USXRA Codes
Solar xray events..
Example:
Definition of symbols:
 USXRA comes from Solar XRAy events
 I I I I I = station indicator
 Y = last digit of year
 MM = month of year, 01 = January, 02 = February, etc
 . DD = UT day of month
 SS = satellite
 06 = GOES6
 07 = GOES7
 08 = GOES8
 09 = GOES9
 E = energy range
 1 = .1.8 nm
 NN = number of events

 0 = indicates that the begin time of the event follows
 HHmm = UT hour and minute of beginning of event

 0 = indicates that the maximum time of the event follows
 HHmm = UT hour and minute of maximum for event

 0 = indicates that the the end time of the event follows
 HHmm = UT hour and minute of end time of event
 Maximum Flux:
 Q = qualifier
 0 = uncertain data
 1 = certain data
 ab = xray flux in Wm^{1} where ab = a.b
 S = sign of the exponent to apply to a.b

 0 = positive
 1 = negative
 p = power of ten to apply to a.b
Note: abSp reported as 4192 would equal 4.1 x 10^{1}Wm^{1}
Note: / is to be used for data not available.
 Integrated flux (start thru end):
 9 = qualifier
 ab xray integrated flux in Jm^{1} where ab = a.b
 S = sign of the exponent to apply to a.b
 0 = positive
 1 = negative
 p = power of ten to apply to a.b
Note: abSp reported as 5692 would equal 5.6 x 10^{1}Wm^{1}
Note: / is to be used for data not available.
