NAME: autocal PURPOSE: Automatic program for creating CCD calibration files. DESCRIPTION: CATEGORY: CCD data processing CALLING SEQUENCE: autocal 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. KEYWORD OUTPUT PARAMETERS: COMMON BLOCKS: SIDE EFFECTS: RESTRICTIONS: 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.
