Chapter 6
BAT Analysis Issues
6.1 Introduction
This chapter contains various science analysis issues that may come up during analysis. In some
cases, the issues represent “bugs” in the software, which are usually corrected in later software
releases. In other cases, the issue may reflect a “gotcha” or other subtle problem that needs special
attention.
The chapter is organized into two sections. The first section contains “current” issues that
may affect analysis of data in the archive today, using recently available software. Users should
definitely consult this first section for any issues that might affect their data analysis.
The second section contains older issues that are not likely to affect present-day analysis. This
involves softare bugs that have been fixed more than a year ago, Swift Data Center problems that
have been fixed, and other issues that have since been resolved.
Each issue contains vital information, such as the versions of the software and which tasks it
affects, the status of the issue, and a more complete narrative about the problem.
6.2 Current Issues
6.2.1 batoccultgti: Fails when checking the field of view only
Task: batoccultgti
Version: 2.3 and earlier
What builds: HEASoft 6.3.1 and earlier
Problem: batoccultgti reports an error ”could not create ’’”
Status: Workaround
Updated: 30 Jul 2007
The task batoccultgti can be used to select times when a particular source is both unocculted
by the earth, and in the field of view. There are several field of view selection criteria, including
both partial coding and instrument coordinates such as IMX, IMY, and theta.
However, if the user selects only instrument coordinate constraints, then batoccultgti will report
the following error:
ERROR: could not create ’’ at /path/name/...
Task batoccultgti 2.3 terminating with status -1
