    Convert Flux
Click For Summary
To convert flux from counts/cm²/sec to erg/cm²/sec for a specific energy band, multiply the number of counts by the energy of the photons in keV and then convert keV to erg using appropriate conversion constants. Each count represents a photon at a specific energy level, so this multiplication is essential for accurate conversion. The discussion also highlights a misunderstanding regarding the graph's axes, clarifying that the bottom axis represents time in modified Julian date (MJD). Overall, the conversation centers on the conversion process and the need for precise energy values. Accurate conversion is crucial for interpreting astronomical data effectively.

Hello everyone.
I am trying to translate the flux of a source observed by a telescope, in different units.
In my case, I have the flux equal to counts/cm^2/sec in a given energy band (15-50 keV) and I want to translate this information in erg/cm^2/sec, in the same energy band
Here you can find an example: http://heasarc.gsfc.nasa.gov/docs/swift/results/transients/weak/GX304-1.png

Does anyone know how can I do that?

Every suggestion is really appreciated.
Ciao

each count is just a photon with that specific energy level, so you just have to multiply the number of photons by the energy of the photons. Then of course convert from keV to erg, which just means multiplying by some conversion constants.

er wait, I think I misread the graph, sorry >.> what's on the bottom axis?
 
The time, in MJD (modified julian date, it is like "days").
 
oh, I see, I'm sorry but I thought I could help but I don't know either
 

Thread 'Luminous Fast Blue Optical Transients (LFBOTs)'

UC Berkely, December 16, 2025 https://news.berkeley.edu/2025/12/16/whats-powering-these-mysterious-bright-blue-cosmic-flashes-astronomers-find-a-clue/ AT 2024wpp, a luminous fast blue optical transient, or LFBOT, is the bright blue spot at the upper right edge of its host galaxy, which is 1.1 billion light-years from Earth in (or near) a galaxy far, far away. Such objects are very bright (obiously) and very energetic. The article indicates that AT 2024wpp had a peak luminosity of 2-4 x...
