UVCOPY UVCOPY is a program which copies one Merge-format file to another. It has options to select a subset of the data by time (UT), UV distance (radius in the uv plane), or amplitude. Example $ uvcopy INPUT = [SCRATCH]3C179P.MRG OUTPUT = 3C179Q.MRG UVRANGE = 50e6, 100e6 / Parameters End the list of parameters with a slash (/). Quotation marks are only needed if the value includes spaces or commas. INPUT and OUTPUT must be specified. INPUT = filename : specifies the name of the input file. OUTPUT = filename : specifies the name for the output file. HISTORY = "text" : the specified text (up to 80 characters) will get written in the history of the output file. The values of the UVRANGE and TIMERANGE parameters are also written in the history. UVRANGE = uvmin, uvmax : select data in the specified uv range; data with uv distance less than uvmin or greater than uvmax will be discarded. The units of uvmin and uvmax are wavelengths. AMPRANGE = ampmin, ampmax : select data in the specified amplitude range; data with amplitude outside this range will be discarded. The units of ampmin and ampmax are those of the data, usually Jy. TIMERANGE = day1, ut1, day2, ut2 : select data in the specified range of UT; data taken earlier than ut1 or later than ut2 will be discarded. Example: TIMERANGE = 127, 03:00:00, 127, 04:00:00 selects data taken between 3 h and 4 h UT on day 127. History Version 1.0: 1989 Jul 12 (T.J. Pearson). Version 1.1: 1989 Oct 31: correct error in dimension of ADDHIS. Version 1.2: 1990 Nov 13: remove unused variables. Version 1.3: 1993 May 14: accept level 2 merge files; add AMPRANGE; maximum 40 stations.
