## Listing Scientifically Valuable Results

Command `PRINT` offers a way to list a number of valuable information on screen or in an ASCII/binary file:

- `PRINT FIT`, which prints the results of profile fits. For each spectrum, N lines are written (N being the number of fitted components), and each line contains in the following order (1) the component number, (2) then observation number, (3,4) the two cartography offsets, (5,6) area of Gaussian and corresponding error, (7,8) same for position, (9,10) same for width, (11) intensity, (12,13) rms on the baseline and on the line. Offset are in the current coordinate system and units. The current method is used.

  For Continuum method, only a single Gaussian is written. The written information is oriented towards pointing measurements: (1) the observation number (2,3) Azimuth and elevation (4,5) area of Gaussian and error, (6,7) position, (8,9) width, (10) intensity, (11,12) rms on baseline and signal, (13,14) collimations. All angular values are in the current angle unit. The values are followed by the source name.

- `PRINT AREA`, prints the area of the line computed by the `BASE` command. Each line contains (1,2) offsets, (3) area, (4) rms noise. `PRINT AREA V1 V2 V3 V4 ...`, prints areas within velocity slices (if such is the current X unit, but one could use channels or frequencies). Ranges are V1-V2, V2-V3, V3-V4, ... etc. Each line will contain (1,2) the offsets, followed by the areas in order.
- `PRINT CHANNEL` `List`, prints values of channels in the list. The list is specified in the FOR n1 TO n2 BY n3 format. Total number of channels is however limited to 15.
- `PRINT MOMENT` `V1 V2 V3 V4 ...`, prints moments (area, position, width), of the data within the velocity (or channels or frequencies, depending on the current units) V1-V2, V3-V4, etc... Each line contains (1,2) the offsets, (3,4,5) the moments for V1-V2, (6,7,8) for V3-V4 etc...
- `PRINT POINTING`, prints results of CONTINUUM method fits printed in a format adapted to pointing constants measurements. The output is suited for further processing and determination of pointing constants using the POINT program.
- `PRINT FLUX`, prints results of CONTINUUM method fits printed in a format adapted to flux determination. The output is suited for further processing using the FLUX program.

As all commands using a set of spectra, `PRINT` works on the whole current index. Output is by default printed on the screen, but may be directed onto a file by the `/OUTPUT Filename` option.

Alternatively, the same information may be written to a ``Table'' (a special kind of GILDAS image). The Table format is much faster and suppresses some of the limitations of the formatted output on the number of columns written. Table format is obtained using option `/TABLE Tablename`.
