Inputs

Optional Input Parameters

Keyword Input Parameters

ASK = flag, if set will ask if you want to delete each image in turn
once you don't delete any images in a pass it will then
proceed to finish. If you delete anything, that calibration
file will be regenerated using the modified set you have chosen.
FILKEY = String - FITS keyword to read to get filter code, default = FILPOS
EXPKEY = String - FITS keyword to read to get exposure time, default = EXPTIME
TYPEKEY= String - FITS keyword to read to get exposure type, default = IMAGETYP
OVERSCAN = column overscan region to use for frame bias level,
default=[-1,-1]
CROP = region of original image to save, default=[-1,-1,-1,-1]=no crop
[x1,x2,y1,y2]
DDIR = String, name of directory where data exists. If not provided,
the program assumes the current directory.
ROOT = String, root of file name for data, usually YYMMDD (ut date).
Default is the last part of DDIR.
SCALE - 4 element vector which, if provide, defines the region of the
array dimensions that are used to scale the mean
of the arrays before combining (. If combined in this
manner, the arrays are combined weighted by the means.
[x1,x2,y1,y2] (Used for flats only.)
These coordinates apply to the pixel locations AFTER cropping.
BINFAC - binning factor for display of final products (default=1)
PATTERN - File searching pattern, default=root+'*.???'
RDNOISE - Read noise of CCD [in DN], default=10

Outputs

All output is confined to files.

Procedure

Modification History

2001/02/15 - Marc W. Buie, Lowell Observatory
2001/03/19, MWB, fixed file name bug.
2001/04/24, MWB, fixed problem with incomplete flat sets on a night.
2001/09/25, MWB, forced imagetyp field to be lower case.
2003/10/01, MWB, converted my Filemove call to system file_move routine
converted my Mkdir calls to IDL file_mkdir calls
2003/11/05, MWB, changed file search pattern to get YYMMDD*.???
(the * is new)
2004/9/21, MWB, removed obsolete call to Findfile
2005/4/1, MWB, modified for new version of MKDARK
2005/10/26, MWB, added PATTERN keyword
2006/03/15, MWB, added BINFAC keyword
2007/05/08, MWB, removed unused FILNAMEKEY keyword, modified FILKEY to use
multiple filters (ie., FILKEY='FILTER*')
2008/01/22, MWB, added RDNOISE keyword.
