X-Ray Light Curve of GRO J1744-28 observed with rxte/pca on Day 152 of 1996
J1744_d152_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 may 31 19:08 to 23:01, 1996 (ut), which is almost 3 orbits of XTE. Bin #0 of x-axis corresponds to may 31 19:05:51, 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 four bursts during the observation of GRO J1744-28, however it is not clear if these bursts are from GRO J1744-28.

    power spectrum of GRO J1744-28 on day 152 (may 31, 1996)
    J1744_d152_power image: Power spectrum of GRO J1744-28 observed with rXTE/pca on day 152 (may 31, 1996). Power spectrum of GRO J1744-28 observed with rXTE/pca on day 152 (may 31, 1996). This power spectrum is an ensemble average of 45 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.
