Program: MNMX Purpose: This program finds the minimum and maximum value in a subset or part of a subset. It also counts the number of blanks. Category: CALCULATION, HEADER, MANIPULATION File: mnmx.shl Author: K.G. Begeman Keywords: INSET= Set (and subset(s)) for which to determine the minimum and maximum. Maximum number of subsets is 2048. ** BOX= Area to be searched for minimum and maximum [entire subset]. ** TOFILE= Write result table to file? Y/[N] Hidden keyword. Is set to Y the result table is written to a file on disk in the directory where GIPSY is started. The file has a fixed name. That name is _mnmxtmp_ Notes: 1. MNMX updates the descriptor items DATAMIN, DATAMAX and NBLANK only when working on whole subsets. 2. If subsets have zero dimension, i.e. if they are pixels, then MNMX will display the pixel values. Example: MNMX MNMX ,INSET=AURORA RA -3:4 DEC 0 FREQ 32 Set AURORA has 3 axes RA-NCP from -7 to 8 DEC-NCP from -7 to 8 FREQ-OHEL from 1 to 59 ( RA, DEC, FREQ) DATA VALUE ( -3, 0, 32) -4.0723352 ( -2, 0, 32) -2.8402100 ( -1, 0, 32) -3.8706512 ( 0, 0, 32) 5.0316072 ( 1, 0, 32) -11.610437 ( 2, 0, 32) -6.4864664 ( 3, 0, 32) 4.0308046 ( 4, 0, 32) 3.9248881 MNMX +++ FINISHED +++ Updates: Jan 29, 1990: KGB, Document created. Jun 25, 1997: VOG, Hidden keyword CHANGE= added Keyword is undocumented and for special purposes only. Feb 25, 2013: VOG, Increased filename length to 1024 Nov 10, 2014: VOG, Added keyword TOFILE= to facilitate output in GUIPSY May 30, 2017: VOG, Corrected wrong array len in tabs
