Allows user to change DAOPHOT options. The command OPTIONS by itself will put the user into interactive options mode, where OPTIONS are changed just as they are in standard DAOPHOT. If DAOFILES FILE=file.opt is specified before calling options, OPTIONS will automatically load the options from file.opt and exit; this is useful for batch use. Finally, OPTIONS opt1=val1 opt2=val2 ..., can be used to change the values of the specified options opt1, opt2, etc, on the command line; this is probably the preferred mode of use. In all cases, the options can be specified using the first two letters of the full names listed below
The different options, along with the preset defaults, are:
|FWHM OF OBJECT||=||2.50||FITTING RADIUS||=||2.00|
|PSF RADIUS||=||11.00||WATCH PROGRESS||=||1.00|
|LS (LOW SHARPNESS CUTOFF)||=||0.20||HS (HIGH SHARPNESS CUTOFF)||=||1.00|
|LR (LOW ROUNDNESS CUTOFF)||=||-1.00||HR (HIGH ROUNDNESS CUTOFF)||=||1.00|
|MAXIMUM GOOD DATA-VALUE||=||32766.50||PKRATIO||=||1.00|
FWHM is used by FIND; FITTING RADIUS by MULTISTAR; PSF RADIUS by PSF and MULTISTAR; WATCH by most routines; LS, HS, LR, HR by FIND; MAXIMUM GOOD by many routines; PKRATIO, WEIGHTEXPO, SEPRATIO, WRATIO, CHIRATIO, ISKY, IFIT by MULTISTAR; APPSF, NGAU, NPBOX by PSF.
For most commands, the desired options can be specified on the command line of the relevant command, making the OPTIONS command obsolete. We are still working on full implementation of this, however.
