X-ray Light Curve of GRO J1744-28 observed with RXTE/PCA on day 133 of 1996
|
X-ray light curve of GRO J1744-28 observed with RXTE/PCA.
The source was observed from May 12 15:32 to 16:30, 1996 (UT).
Bin #0 of X-axis corresponds to May 12 15:31:19, 1996.
Bin width of each data is 4 seconds.
Due to the problem with low temperature the observation was
performed with 3 PCU's.
This light curve includes background counts of roughly 240-360
counts/bin.

X-ray Light Curve of GRO J1744-28 in finer time resolution
|
X-ray light curve of GRO J1744-28 observed with RXTE/PCA
with 1-sec time resolution binning.
The source was observed from May 12 15:32 to 16:30, 1996 (UT),
and this light curve covers from 16:15:11 to 16:32:14, 1996
Due to the problem with low temperature the observation was
performed with 3 PCU's.
This light curve includes background counts of roughly 60-90
counts/bin.

Power Spectrum of GRO J1744-28 on day 133 (May 12, 1996)
|
Power spectrum of GRO J1744-28 observed with RXTE/PCA
on day 133 (May 12, 1996).
This power spectrum is an ensemble average of 20 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. Broad peak
structure (QPO?) around WN=18, whose time scale is about 50% faster
than observed on day 131,
is also seen while the significance
of the structure must be examined by detailed analysis.
