(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)
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 new software tool, called fv, for visualizing the contents of any FITS format file is now available. Fv is a general software tool that can be used for viewing, plotting, and editing FITS format data files. The first release of fv has a graphical user interface (GUI) that provides spreadsheet-like widgets to display data in any FITS table or image, a text… (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)
In this paper, optimized combined control of a 9-DoF prototype wheelchair-mounted robotic arm (WMRA) system, consisting of a 7-DoF manipulator and a 2-DoF power wheelchair, is demonstrated using vision-based dual-trajectory control that generates separate wheelchair and end-effector trajectories. Physical results of this work are provided with a “Go… (More)
This paper describes recent improvements to the FITSIO subroutine library and the fv FITS file viewer and editor, both of which were initially described at previous ADASS conferences.
