gamit/makex/rhead.f: For Glonass processing: Removed code that set P2 to x2 when
C2 available. Made P2 be secondary choice to C2 so that files with C2 in
header but no C2 data, will include the P2 data in the x-file. TAH 20200526
gamit/makex/rbatch.f: Added back feature to have blank line act as EOF in batch
file. TAH 20200526
gamit/lib/sel_obtyp.f: Fixed initialization loop to 6 (from 4) for iobtypx;
Changed secondary choice to P2 for Glonass when C2 in header. TAH 20200526
gamit/lib/rstnfo.f: Updated to allow a gap between end and start times of up to
6 hours. This happens with firmware updates where the gap can be 1-minute to a
few hours. There is probably no data in gap but GAMIT is still generating
epochs during the gap (makex and maybe model fatals). Cleaned up indenting
around modified code. TAH 20200524
com/sh_sp3fit: Incorporated GNSS into decoding svs_exclude.dat. Line format is
now Gnn, Rnn, etc. When gnss==G, old nn only designation allowed. Note: doy is
3-digit. TAH 20200524
com/sh_gnss_sel: Fixed issue with hardwired date in find command. Updated help
message. TAH 20200524
com/sh_preproc: Made lfile test name more unique by adding expt and doy to
temporary name (conflicts in parallel runs could lead to zero length
lfiles). TAH 20200523
kf/ctogobs/ctogobs_dd.f: Fixed error in replaced integer do loop. TAH 20200520
tables/otl_FES2014bM_MRG.list: Merged FES2014 list from otl_FES2014bM_IGS.list
and otl_FES2014bM.list generated at Chalmers University. TAH 20200520
kf/track/{theory.f, get_miss.f, track_com.h}: Modified behavior of USE_BLQ
command to allow solid-Earth tide model to be specified (IERS2010 or default
analytic model) and to turn off model completely (NOETIDE). NOBLQ needs to be
given as argument to turn off ocean-tide model (structured this way for
backwards compatibility). TAH 20200520
Wednesday 20 May 2020
com/sh_get_grids: New script from S. McClusky to download grids from
ftp://everest.mit.edu to the current working directory. MAF 20200520
kf/update_pmu/igs_to_pmu.f: Added feature to have UT1 in the PMU file be
generated by integrating the LOD values rather than using the globk estimates.
This can be useful when generating Earth fixed SP3 files from inertial t-
files. TAH 20200518
com/sh_gnss_sel: New script to add GNSS networks to sites.default.yyyy.ddd
files. Assumes that the rinex files have been downloaded so that data types
available in the files can be determined with scan_rinex. TAH 20200518
com/sh_plotvel: Added coast line specification -clw option. Default remains
unchanged. TAH 20200515
com/sh_network_sel: Added feature to update existing sites.defaults file with
additional net names added. Removed default apr_file name. Useful for having
GPS and GNSS networks separate. TAH 20200515
com/sh_rx2apr: Forced rinex header coordinate extraction if RINEX 3 files which
svpos and svdiff can't read. Cleaned up site name extraction when directory
included in site file name. Cleaned up indentation. Remove spherical l-file
output. TAH 20200518
com/sh_rx2apr: Added RINEX 3 trap to use approximate coordinates in RINEX header
if file given with "-site" option is RINEX 3 or results of SVPOS if file given
with "-site" option is RINEX 2 but file given with "-ref" option is RINEX 3.
MAF 20200517
tables/svs_exclude.dat.nanu: Updated following USCG NANU 2020023. MAF 20200515
tables/rcvant.dat: Added STONEX S980 (STXS98), STONEX S980A (STX98A) and STONEX
S990A (STX99A) receivers, and STXS990A (STX99A) antenna. MAF 20200514
Summary of added features and updates. Tuesday, May 12, 2020
- The Gipson 2017 VLBI model updated. Default: added UT1 libration term and
keeps the IERS2010 model.
- New scan_rinex utility added assess observables in RINEX 2 and RINEX 3 files.
- Added pre-fit millisecond clock jump scanning and fixing in autcln. Normally
not needed and default is not to do it. New status report option to look at
pre-scan clock residuals. Useful if lots of BAD PREFIT data delete messages.
- Added lower frequency selection for GNSS processing (makex and sh_gamit -lfreq
option) so G5, C7, E6/7/8 are options of lower frequency instead of G2, C6 and
E5.
- Updated autcln to avoid errors in autcln/solve when some stations are missing
a frequency band completely.
libraries/includes/freq_def.h: Fixed small error in E8 frequency (0.001E6 Hz)
(impact MW-WL looked like LG in cview. TAH 20200512

files need to be downloaded before sh_get_orbits is run. TAH 20200511
kf/ctogobs/{ctog_utils,read_cfheads}.f: Updated save non-zero frequencies when
c-files are read. Solve has problems if the first c-file is missing a
frequency band and autcln could have problem if last c-file is missing
frequencies. This can happen with GNSS data missing standard frequencies at
some sites. TAH 20200511
kf/ctogobs/set_freqs.f: Moved code that saves frequencies to ctog_utils.f and
read_cfheads.f. TAH 20200511

files even if one band is missing (all data would have been deleted).
TAH 20200511
gamit/makex/makex.f: Modified gnss input so that a lower frequency selection can
be passed. For example C7 for the gnss runstring parameter will select C7 as
lower frequency instead of default C6. G5, E6, E7 and E8 are also options.
TAH 20200511
gamit/lib/sel_obtyp.f: Added option for lower frequency selection. TAH 20200511

selection (e.g., G or G5 for L5 lower frequency. TAH 20200511
gamit/makexp/makexp.f: Added passing gnsslf string into makex batch file.
TAH 20200511
com/sh_makexp: Added -lfreq option to select lower frequency for G,C and E, e.g.
"-gnss E -lfreq 7" will select L7 (E5b) as lower frequency for Galileo instead
of L5 (E5a). Options allowed are G5, C7, E6/7/8. TAH 20200511
com/sh_preproc: Added -lfreq option (see sh_makexp). Fixed bug with g-file being
checked with "^G" rather than "^$gnss". TAH 20200511
com/sh_gamit: Added -lfreq option (see sh_makexp); -remakex Y will be needed if
older x-files already exist in processing directory. TAH 20200511
kf/ctogobs/prc_ctog_cmd.f: Added new option to prefit_clk command to remove
millisecond jumps in clocks. Not a common problem but could be useful for some
data. TAH 20200510

scan). TAH 20200510
kf/ctogobs/prescan_clk.f: Added some commented out write statements to print
information on clock fits. TAH 20200510
kf/ctogobs/ctogobs.f: New call to prescan_msj. TAH 20200510

version number for autcln. TAH 20200510
kf/ctogobs/fit_igs_clk.f: Limited updating linear fits to clocks with < 100 ns
RMS. Millisecond jumps in clocks can cause high RMS scatters. Corrected
indexing on frequencies (not issue since all frequencies are mapped to common
frequency at this point). TAH 20200510
kf/ctogobs/upd_cf_sd.f: Removed a debug statement. TAH 20200510
kf/ctogobs/Makefile.generic: Added prescan_msj subroutine. TAH 20200510

calc_hf_gip_xyu. This code is implementation of Gipson 2017 VLBI model. Both
of these routines have same block of code for HF EOP but some time argument
variable names differ. TAH 20200509
gamit/lib/hfeop_gipson.f90: New module implementing Gipson VLBI model. Libration
and solid Earth terms were in a priori so this model needs these terms added
and is compatible with Desai and Sibios implementation. TAH 20200509
gamit/lib/hfeop_desai.f90: Modified to remove functions and subroutines that are
common to hfeop_gipson.f90. TAH 20200509

tables/svs_exclude.dat.nanu: Updated following USCG NANU 2020017. MAF 20200424
com/sh_network_sel: Added a secondary list of stations so that the core list can
contain critical stations (the number of stations can be less than the total
network size). After selection of all core stations, the secondary list is
used for the priority of these stations. Added a -clear_list option to force
the re-download of archive data holdings. TAH 20200422

igs_metadata_2101.snx. MAF 20200416
gamit/orbits/yawtab.f: Added one day to date for call to svnav_read because the
start of the t-file may occur before the start time of a PRN number record.
A. Koulali/R. Pickle/MAF 20200414
com/{sh_dem,sh_plotvel}: Updated to write new .grd-files to current working
directory, rather than ~/gg/maps/; corrected definition of maximum longitude
in "minmax" variable when passing topo_file name from sh_dem to grdimage for
