Mukulski Archive for Space Telescopes (MAST) archive.stsci.edu send questions to: archive@stsci.edu MAST Simple Spectral Access Service Successful metadata query SSAP Search Position in the form "ra,dec" where ra and dec are given in decimal degrees in the (ICRS/FK5) coordinate system. Currently the reference frame format modifier is not supported, nor are multiple sets of ra,dec values. Search diameter in decimal degrees. Default = 0.05 degrees. Note unlike SIAP, only 1 value is specified!) The spectral bandpass specified in a range-list form as vacuum wavelengths in meters (although values > 100 will be treated as Angstroms). Spectra within the 500-550 A range would be requested as BAND=5.0E-7/5.5E-7. Spectra containing data at 2000A is specified as a single value 2e-07. Note: only numerical values are currently accepted and the optional "source/observer" parameters are currently ignored. If not specified, all wavelengths are returned. The observation time specified in a range-list form specified in ISO 8601 format. For example, to specify a range in time TIME=1997-01-01/1997-01-31). Specifies minimum level of flux calibration. Default is to return all. Current allowed values include "ABSOLUTE", "RELATIVE", and "UNCALIBRATED" (the latter returns ONLY uncalibrated fluxes). The output file format, (currently only FITS is supported). If specified, all entries with derived signal-to-noise ratios greater than the specified value will be returned. (Does not support the general range/list syntax.) To see results as an HTML table, specify outputformat=HTML_Table. By default output is in VOTable format. Will search on target name without resolving to coordinates. Can be used to find moving targets (targetname=mars). Wild cards are allowed (e.g., targetname=beta* ) Right Ascension (J2000) Declination (J2000) RA and Dec of target RA and Dec of observation URL of spectrum file Target name Number of data points Exposure time Observation start date Time of start of exposure in MJD midpoint of exposure in MJD Time of end of exposure (MJD) Mime type of file Coordinate system reference frame Epoch Indicates a preview is available Indicates a scrapbook selection Minimum wavelength in spectrum Maximum wavelength in spectrum data set name and target name time reference frame spectrum reference frame version number Date of VO file creation?
