... Both sets of objective transmission gratings consist of hundreds of co-aligned facets mounted to supporting structures on 4 annuli (one for each of the four co-aligned mirror pairs) to intercept the x rays exiting the HRMA. ... The two sets of transmission gratings, attached to the mounting structure are shown in Figure . ... An individual facet has 0.43-m-thick gold grating bars with 50% filling factor and 9920- period, resulting in 1.15-/mm dispersion. The HRC-S is the primary LETG readout. ...

Here's a little better image of SN 1998s from last night (98 Mar. ... I went crazy last night trying to get an image of the new SN without a lot of scattered (the streak of light above the galaxy) light from Chi UMa which is close by. I'm going to change a few things in my camera/reducer setup an try again on the next clear night. I'll send you a better image then. ... Back to Supernovae in NGC and IC galaxies .

... The common identifier of this star system is G89-14. Initially, there were known just two close spectroscopic components in this system, A and B, orbiting around each other with a period of about 190 days (Carney et al., ... Subsequently, at a separation of 34 arc seconds from this spectroscopic pair, Allen et al. (2000) found its companion D with common proper motion (Fig.1, right, and Fig.2). ... The uniqueness of this star is that it is the most metal-poor quadruple system known to date. ...

Starting with the Apache 1.2 betas, people are reporting many more connections in the FIN_WAIT_2 state (as reported by netstat ) than they saw using older versions. When the server closes a TCP connection, it sends a packet with the FIN bit sent to the client, which then responds with a packet with the ACK bit set. ... Some users have observed no FIN_WAIT_2 problems with Apache 1.1.x, but with 1.2b enough connections build up in the FIN_WAIT_2 state to crash their server. ...
