Producing Output Plots, Tables etc.

When all the desired fits have been done (or earlier to get a check on them), you should used the standard FIGARO function HARD to set the hardcopy device (like SOFT for a softcopy device), for example:

% hard ps_l

Then enter the program and at the main menu select ``OUTPUT''. Then enter the options required e.g.:

......
......
Output   : Create output plots, etc.
Exit     : Leave program
Main menu [MANUAL] - OUTPUT

=========< O u t p u t   O p t i o n s >=========

Hardcopy : Plots of profile fits.............. F
Table    : Table of profile parameters........ F

Exit     : Exit menu
Output Options - TABLE

The selection of options here is to ``toggle'' the option on or off, so entering an option once will select it, twice will cancel the selection. The options are performed when this menu is left.

 Date:- 339/1/1984
 UT 17 51 13
 Observatory position 149 3 57.91 -31 16 37.34

If the program cannot find information on the observatory, then it will ask. The reply can be the position, or an observatory name (type ``HELP'') for help. Likewise the position of the object, date of observation etc. will be prompted for if required. Note that it is satisfactory to give the date as (for example) the 60th day of the year, giving the month as 1, rather than giving the true month, if this is preferred.

The velocity may be corrected to heliocentric, local standard of rest, galactic, or local group. This uses the STARLINK SLA library (Wallace 1990) and is based on the STARLINK program RV (Wallace 1987).

Unless NOFIT was specified (in which case the user would miss out the main menu entirely), the user is now returned to the main menu.

The option to mark the points can either put the markers so that the most intense 3rd of the points have a filled circle, the next 3rd an open one, and the remainder are not marked, or the area can be proportional to the logarithm of the flux. The latter is recommended.

Note that if NOLABEL is given in the command line the titles will be omitted for many of the output plots.

In some cases LONGSLIT may not have been able to obtain errors on the fits--this involves inverting a matrix. For such cases the errors will be given as zero (obviously not a correct value!) when the fits are listed.
