  We present a method for calibrating the flux density scale for images
generated by the Amsterdam ASTRON Radio Transient Facility And Analysis Centre
(AARTFAAC). AARTFAAC produces a stream of all-sky images at a rate of one
second in order to survey the Northern Hemisphere for short duration, low
frequency transients, such as the prompt EM counterpart to gravitational wave
events, magnetar flares, blazars, and other as of yet unobserved phenomena.
Therefore, an independent flux density scaling solution per image is calculated
via bootstrapping, comparing the measured apparent brightness of sources in the
field to a reference catalogue. However, the lack of accurate flux density
measurements of bright sources below 74 MHz necessitated the creation of the
AARTFAAC source catalogue, at 60 MHz, which contains 167 sources across the
Northern Hemisphere. Using this as a reference results in a sufficiently high
number of detected sources in each image to calculate a stable and accurate
flux scale per one second snapshot, in real-time.
