The short time-scale variability in the X-ray flux of the quasi-periodic oscillations (QPOs) and low-frequency noise (LFM) in GX 5-1 is examined, using data from Ginga observations and simulations of the GX 5-1 power spectrum, with the purpose of determining whether there is an association between the LFN and the QPO in GX 5-1 on the horizontal branch (i.e., whether the LFN shots are the envelope of the QPOs). It is shown that the GX 5-1 data contain no indication that QPOs are carried by positive shots. Simulations also revealed no indication of a correlation between the QPO and the LFN components. The results are consistent with a picture of QPOs produced independently from an intensity-symmetric LFN component.
