2MASS LMC/SMC Calibration Merged Point Source Information Table
Photometric calibration for 2MASS was performed using observations of calibration fields made at regular intervals during each night of survey operations. Measurements of standard stars in the fields were used to derive the photometric zero point offsets as a function of time during each night. Atmospheric extinction coefficients were derived from 2MASS observations made over long periods.2MASS calibration fields, or tiles, are 1° long in declination and approximately 8.5' wide in right ascension. There are 35 regular survey calibration fields distributed at approximately two hour intervals in right ascension near declinations of approximately -30°, 0° and +30°. An additional five calibration fields were defined in and around the Large and Small Magellanic Clouds to support the deep observation (6x) campaign towards the end of survey operations.Over the course of the survey, the regular calibration fields were scanned between 562 and 3692 times in nominally photometric conditions. Equatorial fields were observed from both observatories, so were observed more frequently than those near ±30° which were observed with only one telescope. The special Magellanic Cloud calibration fields were observed 108 to 468 times between November 2000 and February 2001.The following table contains brief descriptions of the entries in the Survey, 6x and Calibration Merged Point Source Information Tables. The merged source tables contain the mean positions magnitudes and uncertainties for sources detected multiple times in each of the 2MASS data sets. The merging was carried out using an autocorrelation of the respective databases to identify groups of extractions that are positionally associated with each other, all lying within a 1.5" radius circular region. A number of confirmation statistics are also provided in the tables that can be used to test for source motion and/or variability, and the general quality of the merge.

FIELD EXP EARTH PARABOLA CALIBRATED RDR SPECTRUM V1.0
PARABOLA data were obtained at three GRSFE modeling sites in the Lunar Crater Volcanic Field. The playa site, the cobble site, and the mantled flow site. Each site was imaged by PARABOLA at a variety of solar incidence angles to characterize the scattering properties of the surface completely. This information can be used as a reference to correct airborne data from ASAS and AVIRIS from any lighting and viewing geometry, or as a base data set to test radiative transfer models. Six sets of data from the playa site were gathered primarily on July 17, 1989 with solar incidence angles that varied from 28 to 71 degrees. Five sets of cobble site data were gathered during the morning of July 18, 1989 with incidence angles from 19 to 57 degrees. Data from the mantled flow site was obtained six times during the afternoon of July 18 with incidence angles from 21 to 73 degrees. In all, over 1000 data points exist for each site to characterize its scattering properties. Additionally, an equal number of points exist for the sky above the sites.
NEW HORIZONS SWAP JUPITER ENCOUNTER CALIBRATED V4.0
This data set contains Calibrated data taken by the New Horizons Solar Wind Around Pluto instrument during the Jupiter encounter mission phase. This is VERSION 4.0 of this data set. During the Jupiter mission phase, SWAP made near-continuous science observations, taking data between 2 and 12 times per hour. Inbound to Jupiter, real-time science mode data were taken twice per hour, then 12 measurements were recorded per hour in the Jupiter tail. The Jupiter tail observations continue until about 100 days after closest approach, which corresponds to about 2200 RJ downstream. The changes in Version 4.0 were re-running of the ancillary data in the data product, updated geometry from newer SPICE kernels, minor editing of the documentation, catalogs, etc., and resolution of liens from the December, 2014 review, plus those from the May, 2016 review of the Pluto Encounter data sets. No new observations were added with Version 4.0.
CASSINI SS/S RPWS CALIBRATED LP POTENTIAL CURRENT V1.0
The Cassini Radio and Plasma Wave Science (RPWS) Langmuir Probe Sweep voltage-current data set comprises calibrated Voltage-Current (U-I) characteristics acquired almost continuously from most mission phases during the entire Cassini mission. The full data set of Voltage-Current characteristics is intended to become the most comprehensive and complete data set from which thermal plasma parameters can be derived in the Cassini RPWS archive. Data are presented in text tables and are organised so as to have fixed-length records for ease in data handling. These can be used to derive higher level data products like thermal plasma parameters, e.g., electron density and temperature.
GALILEO ORBITER AT JUPITER CALIBRATED MAG HIGH RES V1.0
This data set contains high time resolution magnetic field vectors acquired by the Galileo magnetometer (MAG). It includes both satellite flyby and non-flyby data. These data were acquired in order to characterize various portions of the Jovian magnetosphere at high time resolution. The Galileo Magnetospheres Working Group (MWG) collectively acquired high time resolution data for short intervals in order to try and regain some of the magnetospheric science lost due to the low data rates of the phase 2 mission (no high gain antenna) mission. These observations are scattered in Jovian distance, local time, System III longitude, etc. in order to provide some insight into processes that may be active in different regions of the magnetosphere.
CASSINI V/E/J/S/SS RPWS CALIBRATED LOW RATE FULL RES V1.0
The Cassini Radio and Plasma Wave Science (RPWS) calibrated full resolution data set includes all spectral information calibrated in units of spectral density for the entire Cassini mission. This data set includes calibrated values for each frequency channel for each sensor for all times during the mission including the two Venus flybys, the Earth flyby, the Jupiter flyby, interplanetary cruise, and the entire Saturn tour. Data for this data set are acquired from the RPWS Low Frequency Receiver (LFR), Medium Frequency Receiver (MFR), Medium Frequency Digital Receiver (MFDR) (which can be used to replace MFR band 2 data) and High Frequency Receiver (HFR). Data are presented in a set of tables organized so as to have fixed-length records for ease in data handling. This data set is intended to be the most comprehensive and complete data set included in the Cassini RPWS archive. A browse data set is included with these data which provides for a graphical search of the data using a series of thumbnail and full-sized spectrograms which lead the user to the particular data file(s) of interest. This data set should be among the first used by a user of any of the RPWS archive as it will lead one to information required to search for more detailed or highly specialized products.
