X-Ray Light Curve of GRO J1744-28 observed with RXTE/PCA on day 156 of 1996
J1744_d156_16s_lc image: X-ray light curve of GRO J1744-28 observed with RXTE/PCA. Bin width of each data is 16 seconds. X-ray light curve of GRO J1744-28 observed with RXTE/PCA. The source was observed from June 4 14:19-18:34, 1996 (UT), which is almost 3 orbits of XTE. Bin #0 of X-axis corresponds to June 4 14:15:11, 1996. Bin width of each data is 16 seconds. This observation was done with 5 PCU's. This light curve includes background counts of roughly 1600-2400 counts/bin.
XTE detected eight bursts during the observation of GRO J1744-28, however it is not clear if all of these bursts are from GRO J1744-28.

    Power Spectrum of GRO J1744-28 on day 156 (June 4, 1996)
    J1744_d156_power image: Power spectrum of GRO J1744-28 observed with RXTE/PCA on day 156 (June 4, 1996). Power spectrum of GRO J1744-28 observed with RXTE/PCA on day 156 (June 4, 1996). This power spectrum is an ensemble average of 83 spectra, each of which are calculated from 128 seconds continuous data in 0.125 second bin. X-axis represents wave number (WN). Frequency of each WN is given as WN/128 (Hz). Peak at WN=274 (2.14Hz) corresponds to the coherent pulsation.
