* Command file for AUTCLN version 3.125 to be used for global and regional data * Default values are listed with comment flag (non-blank first character) * Last edited by tah/rwk/scm 061204 * Don't use any GAMIT edits use_gamit no * Remove more bias flags by allowing a base satellite if multiple slips allow_one_bg yes * If needed to increase the number of channels (compiled default is now 15) max_chan 32 * Allow up to three missing epochs before flagging a data point; this helps with * hourly telemetry gaps and seems to do no harm otherwise gap_size all 3 * Set minimum elevation for editing and output: 15 10 better for older receivers * also sets minimum SNR site_param all 7 7 0 0 * Set the ionospheric tolerances so you don't throw out too much data. * These are the current defaults and will work under both low and high * ionospheric conditions with well-behaved receivers. For poorly tracking * receivers and low ionosphere, you can improve the editing using * 240 4 0.3 0.8. * ion_jump all 30 6 2 5 * Criteria for detecting slips (initial bias flags). Defaults shown. * First three are for WL, irrelevant for codeless L2 receivers * Second three (LC) might be set tighter (e.g. 4 0.2 0.5) to catch * partial-cycle jumps with poorly performing receivers. * With poor prefit coordinates, set the last two numbers to 2 5 (or 5 10) * but use the defaults for POST or, with noisy data, skip the postfit * edit until a second pass with good coordinates allows tight detection of jumps. * dd_fit_tol 5 2 10 3 0.35 0.8 * The following three commands control the repair of cycle slips and subsequent * removal of bias flags. The default values are conservative in the sense * that they retain the most data. They are optimal for global networks but * will work ok also for regional networks. However, for better ambiguity * resolution in regional networks, different values are optimal. * * Set the tolerances used in trimming the one-way data to remove small * segments between bias flags. The following are defaults: * trim_oneway 120 8 0.1 24 * For regional networks use trim_oneway 1000 10 0.2 50 * The first two parameters are the minimum times in seconds and minimum * epochs for attempting to remove a bias flag; the last two are the minimum * fraction of total span and minimum number of epochs allowed after last bias * flag. To strengthen ambiguity resolution for regional data, increase the * last two parameters. For fewer bias flags in 24-hr data increase the first * two parameters. * * Number of data used to repair cycle slips. Defaults are ok for all data but * all values could be reduced for data sampled less often than 30s. * dd_return_size 100 50 10 10 * * DD criteria for removing bias flags: chi-sq ratio chi-sq min max gap gap scale * For global networks use * remove_bias 10 3 1800 5 * For regional networks use remove_bias 10 3 3600 5 * For fewer flags but more risk over small gaps, decrease the first value (see * autcln.out). For fewer flags and more risk over large gaps, increase the * third and decrease the fourth, * Maximum number of bias flags per SV before deleting all the data. * Default infinite (not checked). max_scan_edit 30 * To enhance numerical stability in SOLVE (but be careful in interpreting * one-way residuals) apply_phs_clk 1 * Set the summary filename to agree with the command file produced by FIXDRV summary autcln.prefit.sum * Exclude L1-only (or bad RINEX files) to avoid problems: comment out if you want to process L1 data noL1only * Commands to be used if post-fit editing invoked in the sestbl.
