HST previews are not currently working. We are investigating and apologize for the inconvenience. For image previews we suggest that you try the Aladin option, and for spectral previews the SpecView option. Links to these options are found near the bottom of the preview page. For ACS, STIS and NICMOS grism data you may find the HLA another good option.

User Specified Search Field

You may now search on any column in the mission database. Select the field you wish to search on and type in the qualification. NOTE that if you choose a field in BOTH the form and in the User Option field, then you may not get results or the result you expect.

In the table below is a list of all the column names available for search. Where reasonable a range or set of valid values is listed. Additional useful notes are included. If you click on the field name, a more detailed description of the data will be found. The column label is used in the search forms and search results. The column name needs to be specified for GET requests.

Column Name	Column Label	Data Type	Valid Values	Notes	UCDs
imaps_filename	File Name	char	imap1_0079.fits	File name specifying imaps1 or imaps2 and exposure sequence number from 79 to 721	ID_MAIN
imaps_target_name	Target Name	char	ZETA PUP	Name of target	ID_TARGET
imaps_ra2000	RA (J2000)	double		right ascension in J2000 in decimal degrees	POS_EQ_RA_MAIN
imaps_dec2000	Dec (J2000)	double		declination in J2000 in decimal degrees	POS_EQ_DEC_MAIN
imaps_obs_start_time	Obs Start Time	char	1993-09-16 16:08:10	Starting time in GMT of first exposure for the given target	TIME_DATE
imaps_category	Category	long	26	The object category based on the IUE classification system, described by a number from 1 to 99.	CLASS_CODE
imaps_hd_num	HD Number	long	10144	The Henry Draper catalog number.
imaps_seq_num	Sequence Number	long	79 - 721	The Exposure sequence number (from 79 to 721) describing the order in which targets were originally observed.
imaps_echelle_pos	Echelle Pos	char	1-4, B	Position of Echelle grating (a number from 1 to 4) or whether a background exposure (B) was obtained. Each grating position covers 1/4 of each echelle order, so four exposures are needed to cover entire echelle spectrum.	OBS_PARAM

imaps_x_offset	X offset	long		exposure offset in x direction	OBS_PARAM
imaps_y_offset	Y offset	long		exposure offset in y direction	OBS_PARAM
imaps_glong	Galactic Long.	float		galactic longitude in decimal degrees	POS_GAL_LONG
imaps_glat	Galactic Lat.	float		galactic latitude in decimal degrees	POS_GAL_LAT
imaps_elong	Ecliptic Long.	float		ecliptic longitude in decimal degrees	POS_EC_LONG
imaps_elat	Ecliptic Lat.	float		ecliptic latitude in decimal degrees	POS_EC_LAT
imaps_data_id	Data ID	char	IMAPS1_0107	File ID (same as file name).	ID_MAIN
