NAME

setimpars -- save / restore the daophot parameters for a particular image

USAGE

setimpars image restore update

PARAMETERS

image
The image for which the daophot parameters are to be saved or restored.
restore
If restore = yes, parfile is "", and the file "image.pars" exists, SETIMPARS sets the current algorithm parameters by reading in the file "image.pars". If parfile is not "", then restore is automatically assumed to be yes.
update
If update = yes, SETIMPARS saves the new current values of the DAOPHOT algorithm parameters in the file image.pars and any previously existing file of the same name is overwritten.
review = no
Review and/or edit the values of the parameters in the parameter sets DATAPARS, FINDPARS, CENTERPARS, FITSKYPARS, PHOTPARS, and DAOPARS by calling up the EPAR task for each of the named parameter sets in turn?
parfile
The name of the input file containing the values of the DAOPHOT algorithm parameters to be restored. If defined parfile must have been written by SETIMPARS. If parfile is null (""), SETIMPARS searches for a file named image.pars in the user's current directory. If no file is found, the DAOPHOT algorithm parameters are restored from the files datapars , findpars , centerpars , fitskypars , photpars , and daopars .
datapars = ""
The name of the file containing the DATAPARS parameter values. Datapars must be a named DATAPARS parameter set file written by the EPAR task, or "" in which case the default DATAPARS parameter set in the user's uparm directory is used. If the parameter unlearn is "yes" and datapars is "", DATAPARS is unlearned.
findpars = ""
The name of the file containing the FINDPARS parameter values. Findpars must be a named FINDPARS parameter set file written by the EPAR task, or "" in which case the default FINDPARS parameter set in the user's uparm directory is used. If the parameter unlearn is "yes" and findpars is "", FINDPARS is unlearned.
centerpars = ""
The name of the file containing the CENTERPARS parameter values. Centerpars must be a named CENTERPARS parameter set file written by the EPAR task, or "" in which case the default CENTERPARS parameter set in the user's uparm directory is used. If the parameter unlearn is "yes" and centerpars is "", CENTERPARS is unlearned.
fitskypars = ""
The name of the file containing the FITSKYPARS parameter values. Fitskypars must be a named FITSKYPARS parameter set file written by the EPAR task, or "" in which case the default FITSKYPARS parameter set in the user's uparm directory is used. If the parameter unlearn is "yes" and fitskypars is "", FITSKYPARS is unlearned.
photpars = ""
The name of the file containing the PHOTPARS parameter values. Photpars must be a named PHOTPARS parameter set file written by the EPAR task, or "" in which case the default PHOTPARS parameter set in the user's uparm directory is used. If the parameter unlearn is "yes" and photpars is "", PHOTPARS is unlearned.
daopars = ""
The name of the file containing the DAOPARS parameter values. Daopars must be a named DAOPARS parameter set file written by the EPAR task, or "" in which case the default DAOPARS parameter set in the user's uparm directory is used. If the parameter unlearn is "yes" and daopars is "", DAOPARS is unlearned.
unlearn = no
Return the values of the parameters in the parameter sets DATAPARS, FINDPARS, CENTERPARS, FITSKYPARS, PHOTPARS, and DAOPARS to their default values?

DESCRIPTION

SETIMPARS saves and restores the DAOPHOT task and algorithm parameters for the image image . On startup SETIMPARS initializes all the DAOPHOT package input and output coordinates and photometry file names, input and output images, and input and output plot files to their default values or image whichever is appropriate. Next SETIMPARS reads in the values of the algorithm parameters from parfile if it is defined, or from the file image.pars if it exists and restore is "yes", or from the named parameter set files datapars , findpars , centerpars , fitskypars , photpars , and daopars if they exist, or from the default parameters sets in the user's uparm directory. If unlearn is "yes", these default parameter sets are unlearned.

If review is "yes", the user can review and or edit the newly set algorithm parameters in DATAPARS, FINDPARS, CENTERPARS, FITSKYPARS, PHOTPARS, and DAOPARS using the IRAF EPAR task.

If update is "yes", SETIMPARS saves the new current values of the DAOPHOT algorithm parameters DATAPARS, FINDPARS, CENTERPARS, FITSKYPARS, PHOTPARS, and DAOPARS in the file image.pars . Any previously existing file of the same name is overwritten.

EXAMPLES

1. Save the current values of the daophot task and algorithm parameters for the image m92v.

	da> setimpars m92v no yes

	    ... m92v parameters are saved in m92v.pars

2. Make some minor alterations in the current values of the m92v algorithm parameters and save the new parameters set.

	da> setimpars m92v no yes

	    ... m92v parameters are saved in new version of m92v.pars

3. Begin work on the image m92b. Initialize the values of the daophot task and algorithm parameters for m92b using those stored for m92v. After doing some preliminary editing and reductions for m92b, save the parameters, and return to work on m92v.

	da> setimpars m92b yes no parfile=m92v.pars

	    ... current parameters for m92v are set using saved
		m92v parameters

	da> daoedit m92b

	    ... edit the parameters as necessary for the new image

	da> daofind m92b

	    ... find the stars in m92b

	da> phot m92b

	    ... do the initial photometry for stars in m92b

	da> setimpars m92b no yes

	    ... current m92b parameters are saved in m92b.pars

	da> setimpars m92v yes no

	    ... m92v parameters are restored from m92v.pars
