The positions of these two filter mechanisms are recorded as two adjacent digits in the data, so we can treat them as a single filter code; the second digit is 1 when the ``neutral'' filter is in the beam. There is also a shutter whose position is encoded separately in the data stream: 0 means open, 1 means shut. ...

... XRB SEDs | ... By using RXTE to determine the spectral state of a system we intend to generate SEDs using data that may have been taken at different times but were taken at similar X-ray states. Due to its all-sky coverage and long operational time, the RXTE/ASM instrument provides unparalled information on the spectral states: an ideal jumping-off point for studying time-dependent properties of X-ray binaries. ... Blue arrows designate X-ray observation times. ...
