(FITS) was published, there have been several significant developments in the FITS community: • The International Astronomical Union FITS Working Group (IAUFWG) has endorsed the image (IMAGE) and binary table (BINTABLE) extensions and the agreement on physical blocking. • The proposal for treatment of world coordinate systems has been expanded and refined.(More)
X-ray binaries in the Milky Way are among the brightest objects on the X-ray sky. With the increasing sensitivity of recent missions, it is now possible to study X-ray binaries in nearby galaxies. We present data on six luminous sources in the nearby spiral galaxy, M101, obtained with the Chandra ACIS-S. Of these, five appear to be similar to ultraluminous(More)
1 Overview This document describes a convention for compressing FITS binary tables that is modeled after the FITS tiled-image compression method (White et al. 2009) that has been in use for about a decade. The input table is first optionally subdivided into tiles, each containing an equal number of rows, then every column of data within each tile is(More)
A tsunami of astronomical data is fast approaching. New survey programs will dwarf any data sets that have come before. Obser-vatories' data storage costs will threaten their budgets. Data transport latency and bandwidth will threaten not just budgets, but available technology and human patience. Under such circumstances, projects will increasingly rely on(More)
This paper describes a simple means for embedding a checksum within a FITS header, providing a mechanism for later verifying the integrity of the FITS le. The method uses ASCII coded 32-bit 1's complement arithmetic to force the checksum of each FITS HDU to zero. This technique requires no extension of the FITS standard to be used by any given project, in(More)
A deep (98.2 ks) Chandra Cycle-1 observation has revealed a wealth of discrete X-ray sources as well as diffuse emission in the nearby face-on spiral galaxy M101. From this rich dataset we have created a catalog of the 110 sources from the S3 chip detected with a significance of > 3σ. This detection threshold corresponds to a flux of ∼ 10 −16 ergs cm −2 s(More)
—Two prototypes of a 9-DoF wheelchair-mounted robotic arm (WMRA) have been developed as assistive devices, consisting of a 7-DoF robotic arm and a 2-DoF power wheelchair. Combined kinematics and redundancy resolution have been previously implemented. In this work, we focus on control methods to allow autonomous mobility and manipulation for the execution of(More)
