QUZCIF Source Files Release Notes QUZCIF (July1994) ftools.caltools QUZCIF (July1994) NAME QUZCIF -- Returns the location of calibration files USAGE quzcif mission instrument detector filter codename date time expr DESCRIPTION This task is an interface to the Calibration Database access software. It writes to the standard output all datasets in the Database which meet the selection criteria as specified by the input parameters. Each dataset is printed in two fields, the filename field and the extension number field. The filename field contains the complete directory path to the file containing the calibration data, and the extension number field contains an integer indicating the FITS extension where the data resides. (All calibration files in the Calibration Database are in FITS format.) Each field is separated by spaces. Datasets which are stored in an off-line media (e.g. magnetic tape) will be displayed in the same way except that the word 'OFFLINE' and the off-line media will appear before the filename and extension number. If no datasets are found, then the message "No datasets found matching selection criteria" is displayed. The detector, filter, and expr parameters may be removed from the selection process by entering a string value of "-" when prompted. The value "now" can be entered for the date and time parameters. This value will cause quzcif to use the current system date and time for the date and time parameters. The expr parameter provides a boolean selection expression for Calibration Boundary parameters. A Calibration Boundary parameter is similar to the other selection parameters mentioned above, but may not necessarily be present for every dataset. Thus, the expr expression provides a flexible way of specifying a varying number of selection criteria. Currently, the boolean expression syntax only contains the arithmetic operator ".eq." and the logical operator ".and.". A typical selection expression might look like: theta.eq.10.and.energy.eq.5 If no expr selection is required, a "-" character should be input at the prompt. Before using this task, the 'CALDB' and 'CALDBCONFIG' environment variables (logicals) must be set. See the Caldb User's Guide for details. PARAMETERS mission [string] The name of the mission for which selected datasets should be valid. instrument [string] The name of the instrument for which the selected datasets should be valid. detector [string] The name of the detector for which the selected datasets should be valid. If a "-" character is input, this parameter will not be used in the selection process. filter [string] The name of the filter for which the selected datasets should be valid. If a "-" character is input, this parameter will not be used in the selection process. codename [string] The OGIP codename for the requested data. The value input for this parameter corresponds to the CCNM0001, CCNM0002, ... keyword values found in all Caldb calibration files. Also, the NASA OGIP Memo CAL/GEN/92-011 contains a list of valid codenames and their meanings. This memo can be obtained from anonymous ftp to legacy.gsfc.nasa.gov:/caldb/docs/memos. date [string] The date for which the selected datasets should be valid. This value should be entered in yyyy-mm-dd format (although dd/mm/yy format will also work, with 19yy assumed). LEADING ZEROS *ARE* NOW REQUIRED. If the value "now" is entered, the current system date is used in the selection process. time [string] The time for which the selected datasets should be valid. This value should be entered in hh:mm:ss format. Single digits may be used, but at least a 0 in each value is required. (However, this may change in the future, so using both digits is recommended.) If the value "now" is entered, the current system time is used in the selection process. expr [string] A boolean selection expression for Calibration Boundary parameters. If no expr selection is required, a "-" character should be input at the prompt. (maxret=50) [integer] An integer indicating the maximum number of datasets to print to the screen. Currently this parameter cannot be greater than 50. (nfound) [integer] An integer, returned after the successful completion of this task, which indicates the number of datasets found matching the selection criteria. If this parameter is greater than maxret, the warning message, "Warning: More files were found than are shown here" will be displayed. EXAMPLES 1. Find the location of the ASCALIN dataset for the SIS0 instrument of the ASCA mission valid for Jun 20, 1994. quzcif asca sis0 - - ascalin 1994-06-20 12:00:00 - 2. Find the BKGRND dataset for the GIS2 instrument of the ASCA mission valid for today and for a cut-off rigidity value of 7. quzcif asca gis2 - - bkgrnd now now cor.eq.7 BUGS The current expr parser cannot precheck the expression well. Subexpressions such as "cor.eq.7.and.and.energy.eq.5" will be incorrectly interpreted as "cor=7" and "and.energy=5". A lex & yacc parser is planned for this task which will work much better.
