Recommendation for the operation of the STIS MAMAs during NCS initial turn-on and cool down: It is recommended not to turn on the STIS MAMAs until after 100 hours after the NCS initial turn-on, assuming that the valve heaters are shown to be cycling properly and controlling the value temperatures above their leak level. This recommendation may change depending on the final assessment from the CHAMPS Thermal group of the following risk periods. ...

Next: Other parameters of the Up: The Model Previous: Initial binary parameters . As we only deal with initially massive binary systems (their primary's mass is higher than 10 ), which are capable of evolving off the main sequence during less than years, the compact stars left behind stellar evolution are (in the case of the most massive stars) NSs and BHs. ... For a NS belonging to a binary, the evolution complicates as the secondary star evolves: for example, (recycling), etc. ...

EXPLANATION OF DANA'S FIBER TESTS ON THE 12M TELESCOPE.. ... But we know full well that this is not directly possible- the delay in the optical fiber carrying this signal will change both with temperature and to some degree with fiber bending as the telescope tracks objects or moves from one object to another. ... So we would like to identify at least one pair of single mode fibers in our bundle, whose delay changes due to antenna tracking etc are pretty well matched. ...
