MUDEHaR (MUlti-epoch Disparity Examination of H-Alpha and infraRed) is a multi-epoch photometric survey of two narrow filters: Hα and the calcium triplet window. Using the JAST telescope and T80Cam instrument at the Observatorio Astrofísico de Javalambre (OAJ, Teruel, Spain) is studying 40 square degrees of star forming fields in the Galactic disk. It will detect all kind of variable Hα stars on a days-months-years scale. . Please include the following in any published material that makes use of this data: "Based on observations made with the JAST80 telescope for the MUDEHaR project at the Observatorio Astrofísico de Javalambre, in Teruel, owned, managed and operated by the Centro de Estudios de Física del Cosmos de Aragón." https://archive.cefca.es/catalogues/mudehar-dr1 Catalog Research Copyright © 2025-2026 MUlti-epoch Disparity Examination of H-Alpha and infraRed (MUDEHaR) Survey.

Sample standard deviation of the input values. Sample variance of the input values (square of the sample standard deviation). Slope of the least-squares-fit linear equation determined by the (X, Y) pairs. Y-intercept of the least-squares-fit linear equation determined by the (X, Y) pairs. Square of the correlation coefficient. Correlation coefficient. Sample covariance. The bitwise AND of all non-null input values, or null if none. The bitwise OR of all non-null input values, or null if none. Non-null input values concatenated into a string, separated by delimiter. Convert hour, minute, second to a float degrees value. Convert degrees, arcminute, arcsecond to a float degrees value. Converts a 'time.epoch' (timestamp) to a astronomical Julian Date. Converts a 'time.epoch' (timestamp) to a astronomical Julian Date. Converts a 'time.epoch' (timestamp) to a astronomical Modified Julian date. Converts a 'time.epoch' (timestamp) to a astronomical Modified Julian date. Scalar product of two array. The scalar product of array of unequal length is NaN. Arithmetic mean of the array elements. Sum of all array elements. Largest element in the array. Smallest element in the array. Returns the number of elements in the array. Returns 1 if an element is in the array else returns 0. Returns 1 if any element in the array is NULL else returns 0. You can compute with vectors here. See https://wiki.ivoa.net/twiki/bin/view/IVOA/ADQLVectorMath for an overview of the operators available. Enumerations, it is a form of assign a set of names to a range of values. Writing a enumeration in a query is done by writing the enumeration name, the symbol :: and the item name of the element in the enumeration that we want to use. That is equivalent to write the associated value of the item and it is useful when accessing an concrete element in a array column or using it as a constant.

mudehar.Pointing_blockTable listing characteristics in one pointing, including Julian date and exposure time of each exposure in the pointing. It includes four different exposure times observations (0.1 s + 1s + 10s + 50 s x2) x 5. On average there are 5 valid epochs per star. id Identifier of the pointing block. meta.id char pointing Numerical identifier in the sequence of observation visits to these coordinates. meta.id char field MUDEHaR identifier among the 20 fields observed.

mudehar.SourcesTable listing the main parameters and measurements of the astronomical objects considered in the survey. For each source, the measurements are grouped by pointing block, with each row containing the corresponding data and block identifier. All sources from Gaia and 2MASS are considered, and aperture is selected according to synthetic photometry of the source. Magnitude for stars with any problem in each exposure (weak, saturated, near companion) are included as 99.99. Columns include information compiled from literature (Spectral type), derived from the calibrations or measurements, and coming from the survey characteristics. The calibrator sample are selected according to synthetic photometry fitting, and marked in an specific column. Magnitude data is then adjusted by the ZP with these calibrators. Information on the pointing block in mudehar.Pointing_block, identified by mudehar.Sources.PB_ID. pb_id Identifier of the pointing block. meta.id;meta.main char name_gos Name of the input catalog star.
