Also, printing to A3 should now switch back to A4 properly 930806 NFLAG: Option ARESID for flaggin on Selfcal/Align residuals NFLAG: Option PUT repaired 930802 NSCAN: NVS handles IQUV to XYX conversion properly for more than one channel, proper weight check. 930722 NPLOT: Changed keyword PLUVO in IFR_MODE(normal,spectral,sort) normal: plot ifr vs ha, ifr order (00,01,...,dd) spectral: spectral channel vs ha, per ifr (old PLUVO) sort: ifr vs ha, baseline sort 930706 NPLOT: RULE plots will now be plotted horizontal (C10) 930701 New version of NGCALC with more expression functions and SHIFT Calculate option. The new features can only be used for freshly extracted data; there is no possibility to add the necessary data to the existing NGF files by, e.g. NVS option. Old data can still be used for all other options. 930628 New NPLOT (NGCALC) X11 driver. You can now select the plotsize as fraction of screen (default 0.75; value > 0.0, <= 1.0) by: setenv PGPLOT_XW_WIDTH value and get all plots without waiting (and without seeing end result) by: setenv PGPLOT_XW_CLICKLEFT 0 930622 New NFLAG SHOW SCAN T option to guess calibrator phases selfcal start 930622 Add some flagging possibilities to NGIDS for UV data 930619 A new program: NFLAG contains now the SHOW and FLAG(DELETE) options originally in NSCAN 930616 New option added to set a field shift in SCN (in NCALIB), and to "de-"apply it if wanted (all programs) 930610 Flagging in NSCAN has been redefined, and options added. Read ? text for details 930608 The data format has been changed to cater for multiple flagging layers and absolute (rather than relative) weights per data point. SCN files made before this date will give a message: "run NSCAN/NMAP NVS first". Run NSCAN NVS to convert the data to the new format. "DELETE" is now called "FLAGGING", and a new NGEN keyword UFLAG has been introduced to be able to selectively include flagged data in your processing. Like other NGEN keywords (e.g. APPLY) it can be set as a switch on dwe; a dws NGEN or dws "program" or by dwe "program"/ASK. NSCAN SHOW has been extended to show the flags set for the DATA W option, and a SET_ACTION FLAGS has been added to give an overview of flags per cube slice. 930606 Added ionospheric refraction, baseline pole, d(x,y,x), clock and frequency correction. Limited edges of mosaic output to suppress noisy data 930524 Many keywords now have a more meaningfull name. 930519 Read/Write to DAT-devices on HP now possible 930513 NCALIB/NGCALC: New method for complex Least Squares NPLOT: Solved problem when plotting with one (positive or negative) contour causes crashes. (A42) Problem with keyword DELETE_NODE solved (came in a loop). (A47) NGIDS: Reorganised the program for future (interactive deleting) NMODEL: New option: FIND to find sources in map 930503 NMODEL: Problem with core-dump when type-error solved (A40) Model update was wrong for fields with negative declination. NSCAN: Problem with flagging of two polarisations corrected (A41) NSCAN/NCALIB: Message will be printed when the program creates a new SCN-file. Happens when name of non existing-file typed in (A43) NCLEAN: Problems solved with noise values in the latest restore-step of data-clean (came from original iso. residual map). (A44) NGIDS: now totally independent from GIPSY (A49) NATNF: Phase problem solved (A50) 930304 NMAP: Writing cubes contiguous 930210 NPLOT: Default contours now available. Default PLOTTER will now be PSP, default SIZE will be 1.3, 1.3 920205 The problems on the HP with default value 0 have been solved. Also some printout on the screen will fit on one line. 921222 NPLOT: Display option X11 now partly available for UNIX machines (Do NOT use halftone; some options will NOT work correct yet) 921218 Changed KEYWORD=LOG. All programs have now default YES iso. SPOOL 921106 Programs changed for J2000 and allow HA outside -90 - +90 degrees. 921022 NATNF, NSCAN and NMAP are now able to use mag-tapes on UNIX system. Do a setenv to see which mag-tapes are available. NPLOT and NGCALC can now plot on A3-plotter (B17). 920903 Many problems solved by WNB during his stay in Dwingeloo NGCALC: New program for data calculation and plotting (C2) NATNF: New program to handle RPFITS files NSCAN: Split mosaic data (B1) Error in old WSRT-tapes (1987) .. pointing set (A33) Wrong MJD when not correct ended WSRT observation (A34) Faster mosaic splitsing (2 times faster) (A35) Conversion LINOBS (I,Q,U,V) to XX,XY,YX,YY (B14) NMAP: UV circular weighting function (B5) A option/loop (in FIDDLE/ADD) for line-data (B6) MOSCOM option to use noise as weight (B11) Extended NMAP fits header (B12) Change coordinates if shift (A23) Noise for extract/copy in NMAP (A28) Precission angle calculation (A30) Calculate offsets in map (A32) Logics MAP statistics (A36) NMODEL: Delete of non-clean components (B3) Delete of sources inside dl,dm box (B13) Merge source models: sometimes recalculate everything (A31) RSHOW problem solved (A22) NPLOT: Option to plot hourangle against frequency for a baseline polarisation (C7) Halftone plotting problem solved (A19) Plot message by selfcal/align residuals with model (A24) On SUN: Problem plots bigger than A4 solved (A26) NCLEAN: Changed sign restore beam angle (A20) 920728 NGIDS: New program to load maps into GIDS (GIDS = Groningen Image Display System) 920714 NSCAN updated for Online System nr. 63 (Change in extended FD) 920626 New delete option DCLOW, same as DNCLOW, but for cleaning components NMAP: Problem with Beam-option correctred (B4) Problem with fsum corrected (A18) Problem with model subtraction for polarisation sources with RM corrected (A16) 920623 Name of software-pakket changed from N-series into NEWSTAR (Netherlands East West Synthesis Telescope Array Reduction-package) 920609 NSCAN: Problem with flagging of two polarisations corrected (A12) Layout for MJD(start) corrected (A14) NMAP: Problem with source subtraction corrected (A15) Problem with "LAYOUT" option for WMP-file corrected (A13) 920504 NMAP: Problem with data in HA-baseline format corrected.
