NCCS Output Files from Single-Dish Observing

M J Gaylard, J L Jonas

2002/02/06

This document discusses the content and formats for output files for recording the data from single dish observing with the NCCS. It is proposed that FITS-format files are used to record housekeeping information in the form of keywords and their associated parameters, and data in an accompanying array or binary table. Proposed keywords and their parameters are defined. Typical real-world examples are provided. Written in SGML, this document is viewable from the NCCS documentation index at /usr/local/src/nccs/doc/index.html using Netscape, and can be converted to other formats, e.g. latex, plain-text etc. using SGML-tools.

1. Introduction

1.1 Output files on the HP1000
1.2 Recording data on the NCCS

2. Definition of Keywords and Data for Output Files

2.1 FITS-specific keywords
2.2 Keywords describing the object
2.3 Keywords describing the scan
2.4 Keywords describing the telescope and receiver configuration
2.5 Keywords providing calibration information
2.6 Keywords specific to stepping observations
2.7 Keywords specific to active scans
2.8 Keywords specific to spectroscopy
2.9 Keywords specific to pulsar timing
2.10 Keywords describing the primary data array
2.11 Keywords describing binary tables
2.12 Keywords describing the processing of the data

3. Examples of Output Files

3.1 Output file from a continuum stepping observation
3.2 Output file from a drift scan
3.3 Output file from an active scan
3.4 Output file from spectroscopy
3.5 Output file from pulsar timing
