The product_id is identical to the file name: BTxxxxynnn.img. Where: BT = Brightness Temperature xxxx = Frame Sequence Number y = Latitude Bin. This character gives a latitude range on the lunar surface where the observation was made. The center latitude defines the character. A = -90 to -80 M = 30 to 40 B = -80 to -70 N = 40 to 50 C = -70 to -60 O = 50 to 60 D = -60 to -50 P = 60 to 70 E = -50 to -40 Q = 70 to 80 F = -40 to -30 R = 80 to 90 G = -30 to -20 H = -20 to -10 S = unknown target I = -10 to 0 J = 0 to 10 T = Earth observations prior to K = 10 to 20 systematic mapping L = 20 to 30 U = Sky observations prior to systematic mapping V = Lunar observations prior systematic mapping W = Sky observations after systematic mapping Y = Earth observations after systematic mapping Z = Lunar observations after systematic mapping nnn = Revolution Number mission_phase_name 4 ASCII_String The mission_phase_name element provides the commonly-used identifier of a mission phase. target_name 5 ASCII_String Observed target. revolution_number 6 ASCII_Integer The revolution number refers to an observational pass over the moon. Revolution number is incremented by one each time the spacecraft passes over the south pole prior to the beginning of data acquisition. It is used in lieu of orbit number because is incremented at the equator on the sunlit side of the Moon. Thus, orbit number is changed in the middle of an observational pass. This was awkward in defining data acquired by a single pass over the Moon. frame_sequence_number 7 ASCII_Integer Sequential frame number for an image acquired during a pass over the Moon. start_time 8 ASCII_Date_Time_YMD_UTC Time of start of observation. This time refers to the start of the integration time of the camera. The value contained in this keyword reflects a corrected time. A software problem onboard the spacecraft caused inaccurate times to be attached to an image. This value contains the best estimated time of the observation. product_creation_time 9 ASCII_Date_Time_YMD The time that the data file was created. gain_mode_id 10 ASCII_String Gain mode of the camera, which defines the sensitivity of the detector. offset_mode_id 11 ASCII_String Offset Mode ID specifies the analog value that is subtracted from the video signal prior to the analog/digital converters. exposure_duration 12 ASCII_Real milliseconds Exposure duration (integration time) for an image observation expressed in milliseconds. center_latitude 13 ASCII_Real degree Planetocentric latitude of camera boresight intercept point. center_longitude 14 ASCII_Real degree Planetocentric longitude of camera boresight intercept point. reticle_point_latitude_1 15 ASCII_Real degree Planetocentric latitude of camera principal intercept point 1 - upper left pixel (line 1, sample 1). reticle_point_latitude_2 16 ASCII_Real degree Planetocentric latitude of camera principal intercept point 2 - upper right pixel (line 1, last sample). reticle_point_latitude_3 17 ASCII_Real degree Planetocentric latitude of camera principal intercept point 3 - lower right pixel (last line, last sample). reticle_point_latitude_4 18 ASCII_Real degree Planetocentric latitude of camera principal intercept point 4 - lower left pixel (last line, sample 1). reticle_point_longitude_1 19 ASCII_Real degree Planetocentric longitude of camera principal intercept point 1 - upper left pixel (line 1, sample 1). reticle_point_longitude_2 20 ASCII_Real degree Planetocentric longitude of camera principal intercept point 2 - upper right pixel (line 1, last sample). reticle_point_longitude_3 21 ASCII_Real degree Planetocentric longitude of camera principal intercept point 3 - lower right pixel (last line, last sample). reticle_point_longitude_4 22 ASCII_Real degree Planetocentric longitude of camera principal intercept point 4 - lower left pixel (last line, sample 1). horizontal_pixel_scale 23 ASCII_Real km Distance, measured along horizontal direction, along target surface between intercept points defined by centers of left and right edges of pixel-sized region in FOV centered at camera boresight. Defined only when boresight intercepts surface. Units are in kilometers. vertical_pixel_scale 24 ASCII_Real km Distance, measured along vertical direction, along target surface between intercept points defined by centers of left and right edges of pixel-sized region in FOV centered at camera boresight. Defined only when boresight intercepts surface. Units are in kilometers. spacecraft_altitude 25 ASCII_Real km Altitude of spacecraft above reference ellipsoid in kilometers. Distance is measured to closest point on ellipsoid. north_azimuth 26 ASCII_Real degree Azimuth to target north pole direction vector. The reference line extends from the image center to the right edge of the image. The angle increases in the clockwise direction to the north pole direction. solar_distance 27 ASCII_Real km Distance from target body center to Sun in kilometers. sub_solar_latitude 28 ASCII_Real degree Planetocentric latitude of the apparent sub-solar point. sub_solar_longitude 29 ASCII_Real degree Planetocentric longitude of the apparent sub-solar point. incidence_angle 30 ASCII_Real degree The incidence angle is the angle between the target-Sun vector and the local vertical vector at the boresight intercept. emission_angle 31 ASCII_Real degree The emission angle is measured between the negative of the boresight vector and the local vertical vector at the boresight intercept. phase_angle 32 ASCII_Real degree The phase angle is measured between the boresight intercept-to-Sun vector and the negative of the boresight vector. local_hour_angle 33 ASCII_Real degree The angle from the negative of the target-body-to-Sun vector to the projection of the negative of the spacecraft-to-target vector onto the target's instantaneous orbital plane. The angle is measured in a counterclockwise direction when viewed from North of the ecliptic plane. data_parameter_uncertainty 34 ASCII_Real K The one sigma error value for the brightness temperatures within an image given in Kelvin.
