PROCEDURE: mvn_sclk_test
PURPOSE:
Compares MET to UNIX time conversions for multiple SCLK kernels.
Calculates the error incurred when different versions of the SCLK
kernel are used to convert MET to UNIX time.
USAGE:
mvn_sclk_test
INPUTS:
KEYWORDS:
VER: Integer array indicating the SCLK versions to process.
Default is to analyze the latest six versions.
TRUNC: If set, then for each kernel only process times up to the
release date of the next kernel.
YLIM: Set the vertical plot limits. Default = [0.001,10]
RESULT: Named variable to hold the result.

NAME:
mvn_sclk_version_test
PURPOSE:
compares MAVEN MET to UNIX time conversions for an SCLK kernel with
the most recent kernels. Returns the time ranges for which kernels do
and do not match.
CALLING SEQUENCE:
mvn_sclk_version_test, sclk_name, trange_ok, trange_not_ok, $
test_sclk_name = test_sclk_name
INPUT:
sckl_name = the name of the kernel file, this is typically available
in L2 cdf files.
OUTPUT:
trange_ok = the time range for which the two kernels' values
match. Note that times have resolution of 1 hour
trange_not_ok = the time range for which the two kernels'
values do not match
KEYWORDS:
test_sclk_name = a file name for the kernel to be tested against, the
default is to use the current - most recent kernel file.
dt_tolerance = dt values below this are treated as zero, the default
is 0.0d0

NAME: MVN_SPICE_KERNELS function: mvn_spice_kernels(name) PURPOSE: Provides maven spice kernel filename of specified type Typical CALLING SEQUENCE: kernels=mvn_spice_kernel() TYPICAL USAGE: INPUT: string must be one of: Not implemented yet. currently retrieves ALL files KEYWORDS: LOAD: Set keyword to also load file TRANGE: Set keyword to UT timerange to provide range of needed files. RECONSTRUCT: If set, then only kernels with reconstructed data (no predicts) are returned. OUTPUT: fully qualified kernel filename(s) WARNING: Be very careful using this routine with the /LOAD keyword. It will change the loaded SPICE kernels that users typically assume are not being changed PLEASE DO NOT USE this routine within general "LOAD" routines using the LOAD keyword. "LOAD" routines should assume that SPICE kernels are already loaded.

NAME: MVN_SPICE_KERNELS_UPDATE PURPOSE: Updates all spice kernels from NAIF, should be run from a cronjob once in a while; it can take a long time because all ck kernel files are checked CALLING SEQUENCE: mvn_spice_kernels_update INPUT: none OUTPUT: none, spice kernels are updated $LastChangedBy: jimm $ $LastChangedDate: 2017-03-27 13:38:59 -0700 (Mon, 27 Mar 2017) $ $LastChangedRevision: 23049 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/tags/spedas_6_1/projects/maven/general/spice/mvn_spice_kernels_update.pro $

PROCEDURE: mvn_spice_stat
PURPOSE:
Reports the status of SPICE. This is mainly a wrapper for spice_kernel_info(),
providing a concise summary of the key information. The naming convention for
C kernels (ck) includes a type string:
red = reconstructed, daily
rec = reconstructed, contact-to-contact (typically a few days)
rel = reconstructed, long (typically one week)
pred = predicted
USAGE:
mvn_spice_stat
INPUTS:
KEYWORDS:
LIST: If set, list the kernels in use.
INFO: Returns an array of structures providing detailed information
about each kernel, including coverage in time.
TPLOT: Makes a colored bar as a tplot variable, to visually show
coverage:
green = all kernels available
yellow = S/C spk and ck available, missing APP ck
red = S/C spk available, missing S/C ck
blank = missing S/C spk
which translates to:
green = spacecraft and all instruments
yellow = spacecraft and body-mounted instruments only
red = spacecraft position only
blank = no geometry at all
SUMMARY: Provides a concise summary.
CHECK: Set this keyword to a time array to test whether the loaded
kernels are sufficient to cover the entire time range. The
time array can be in any format accepted by time_double.
If CHECK is set, then keyword SUMMARY will include success
flags (1 = sufficient coverage, 0 = insufficient coverage).
KEY: Print out the color key and return.
SILENT: Shhh.

FUNCTION: MVN_SPICE_VALID_TIMES
PURPOSE:
Checks whether the currently loaded SPICE/kernels are valid for the specified time.
INPUTS:
tvar: Time or time array to be checked.
KEYWORDS:
TOLERANCE: Maximum time difference between input time and nearest valid SPICE coverage.
Default = 120 sec.
SPKONLY: Consider only SPK kernels. Any missing CK information is ignored.
Useful when spacecraft orientation is not needed.
BUSONLY: Consider only C kernels for the spacecraft bus. Any missing CK information
for the APP is ignored. Useful for instruments not mounted on the APP.
