Overview

This document contains an overview of the parameter interface of the program NATNF. The program also uses a number of public interfaces; references to these are also listed.

The remainder of the document describes the individual parameters in alphabetical order. This description centers on the Help texts, which have been designed to guide the user to the proper choice at each junction, even if his knowledge of the overall workings of the program is only superficial.

Parameter CONTINUUM

Prompt: define channels for continuum
Expected input: Integer: 1 to 16 values

A continuum channel can be made by specifying up to 8 pairs of channel numbers.
The channel values will be averaged to produce a single continuum value. Each
pair specifies a low and high channel number to be included.

Special values:
  ""      No continuum wanted
  *       Central 75%

Parameter INPUT_BANDS

Prompt: input bands in cm
Expected input: Real: 1 to 16 values

Specify the bands to be read (20 etc in octave steps. * specifies all bands on
the tape

Parameter INPUT_CHANNELS

Prompt: input channels
Expected input: Integer: 1 to 256 values

Specify the channels (1,..) to be read. * specifies all channels on the tape

Parameter INPUT_FILE

Prompt: input filename
Expected input: Character *80: 1 value

Specify the input filename (without an extension for the LOAD from disk
option).

Parameter INPUT_LABELS

Prompt: input labels
Expected input: Integer: 1 to 256 values

Specify the tape labels to be read. * specifies all labels on the tape

Parameter INPUT_SOURCES

Prompt: sources to get
Expected input: Character *16: 1 to 256 values

Specify the sources to be read. * specifies all sources on the tape

Parameter INTEGRATION_TIME

Prompt: integration time (sec)
Expected input: Real: 1 value

Specify the integration time per scan.

Parameter OPTION

Expected input: Character *24: 1 value

Specify action to perform:

  LOAD    load RPFITS data into scan file
  QUIT    finish

Parameter START_OFFSET

Prompt: scan start offset (sec)
Expected input: Real: 1 value

Often the first 10 sec of a scan are bad. By specifying an offset here, the
first n seconds of a scan will be discarded. E.g. specifying an integration of
70 sec and an offset of 10 sec will produce 4 points for a 5 min observation,
discarding the first and last 10 sec.
