NAME: addnccal PURPOSE: Add calibration frames for entries in the nasacam calib data base DESCRIPTION: Searches the database nasacam.calib table for entries with status=UNKNOWN and attempts to generate appropriate "sub-supers" which are superbias, dark, or flat frames for the given range of images. The constraints on nasacam flat taking (in particular) are such that these super frames will usually need to be combined with others nearby in time, thus the term "sub-supers." After generating (without interaction) what it can, addnccal will update the calname for the rows processed. Ordinarily biases are set to status "GOOD" or "PENDING" based on automatic criteria and flats are set PENDING prior to inspection via the tool chknccal. CATEGORY: CCD data processing CALLING SEQUENCE: addnccal INPUTS: OPTIONAL INPUT PARAMETERS: KEYWORD INPUT PARAMETERS: ABSMOMENT - A 2 element vector giving the maximum value for absolute mean and standard deviation of any superbias generated. This is the baseline test for sub super biases. Current default is [ 5.0, 5.0] based on a cropping region. CALROOT - string giving the path to locate the calibration images referenced in the data base entries, and created by addnccal. The current default is '/kolvir/data1/buie/rawfits/nasacamcal' (on kolvir). COLDTEMPS- An vector of 4 elements giving, respectively, the expected CCD detector temperature, the expected cold head temperature, and the maximum absolute deviations from those levels for individual bias or flat frames to be considered good. The NASACAM default is [-100.0, -160.0, 20.0, 50.0]. This keyword is not implemented and is currently a no-op. CROP - region of original image to save, [x1,x2,y1,y2] default is 2006 NASACAM default of [34, 2064, 2, 2046]. DATABASE - Name of MYSQL database for calibration entries. The default is 'nasacam'. EARLIEST - string in MYSQL date format giving the earliest row in the data base to process. The default is the beginning of time. IMGROOT - string giving the path to locate the image files referenced in the data base entries. The default is '/kolvir/data1/buie/rawfits' (on kolvir). LATEST - string in MYSQL date format giving the latest row in the data base to process. The default is the end of time. MASTBIAS - Absolute path to a fits file which contains a superbias considered good. Superbiases generated by addnccal will be subtracted from this, and the mean and standard deviation of the resulting array is compared with MASTMOMENT. If not specified, this comparison is not made. This keyword is not implemented and is currently a no-op. MASTMOMENT- A 2 element vector giving the maximum absolute mean and standard deviation of the difference array (against MASTBIAS) for a generated sub-super-bias to be considered good. MASTMOMENT is only meaningful if MASTBIAS is specified. The default is [ 300.0, 30.0] This keyword is not implemented and is currently a no-op. NOMEDIANFLAT- Flag, if set, the JUSTMEDIAN flag is not set to MKFLAT when making flats. The default is to set JUSTMEDIAN, which is passed to mkflat and precludes noise clipping and averaging, when making flats. OLEVEL - a 4 element vector giving the expected overscan level and the overscan standard deviation, and the maximum permitted absolute deviations from those levels for individual bias or flat frames to be considered good. The NASACAM default is [2800.0, 10.0, 300.0, 30.0]. This keyword is not implemented and is currently a no-op. OVERSCAN - column overscan region to use for frame bias level, default is 2006 NASACAM default of [2074, 2103]. RDNOISE - Read noise of CCD, DN/pixel, default is 2006 NASACAM default of 9.0 SCALE - For flats, 4 element vector which, if provide, defines 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] These coordinates apply to the pixel locations AFTER cropping. The default is to use the center 50% of the image but not any bigger than 200x200 subsection at the center. This keyword is passed transparently to mkflat. TABLENAME- Name of table in MYSQL database for calibration entries. The default is 'calib'. TEST - Flag, if set, addnccal prints the mkbias, mkflat, and db update commands without running them. It makes the cal subdirectories only. OUTPUTS: No outputs for this procedure. KEYWORD OUTPUT PARAMETERS: COMMON BLOCKS: SIDE EFFECTS: Data base entries are updated and calibration superframes are placed in CALROOT. New subdirectories will generally be created in CALROOT. The calibration superframe outputs will follow the naming convention YYYYMMDD.suf where suf is n.b1 for superbiases and n.f1.f2 for superflats where n represents the ordinal of the entry for that night among raw calibration images of that class, and f1 and f2 are positions on the NASACAM filter wheel. FOR EXAMPLE, if 10 biases and 5 flats each in B,V and methane were taken at each twilght for 20060715, then the cal files would be called 20060715.1.b1 20060722.214.171.124 200607126.96.36.199 200607188.8.131.52 20060715.2.b1 200607184.108.40.206 200607220.127.116.11 20060718.104.22.168 RESTRICTIONS: Assumes images are located in subdirectories named YYYYMMDD for each night. Places calibration products in paths named YYYY/MM/DD for each night. It currently processes data ONLY for the NASACAM CCD on the 31", and there is no support for dark images. Image frame numbers must be in the range 1-999 inclusive. PROCEDURE: MODIFICATION HISTORY: 2006/7/15, Written by Peter L. Collins, Lowell Observatory 2006/7/24, PLC, modified after adding new column startime to calib table, adding "PENDING" as a value for status, changes to order of bias/flat evaluation- in particular, designed to make good/bad choice on sub-super-bias whenever possible automatically. 2006/07/26, PLC,added support from empty returns from mysqlquery. 2006/07/27, PLC,general cleanup and mark unimplemented keywords in header.
