- Automatically renames(add prefix) FITS file according to their headers.
-
--list
- The name of the file containing the list of input files.
-
--rename_by
- FITS keyword to classify images.
-
--reparse
- If
1
, previously classification will be initialized. - Default value is
0
- If
- Find comet in images, and make offset data to align comet in each image.
- The 1st image will be the reference.
-
--list
- The name of the file containing the list of input files.
-
--xrange
,--yrange
- Initial x and y range to search for comet, comma separated.
- Default value is
350,650

--movement_x
,--movement_y
- Maximum shift between each image.
- Default value is
10
.
-
--output
- Name of the output file.
- Default value is
offset.txt
- Filters out the image with significantly different average ADU compared to other images.
-
--list
- The name of the file containing the list of input files.
-
--output
- Name of the output file.
-
--reference
- If given, the reference ADU will be set to given value.
- By default, the reference ADU is average ADU of the first image.
-
--threshold
- Set ADU range to be allowed.
- Default value is
0.2
, which means ± 20% from reference ADU is allowed.
- Classify images by time.
-
--list
- The name of the file containing the list of input files.
-
--fits_header_juliandate
- FITS keyword stores Julian Date(JD.)
- Default value is
JD
.
-
--output_prefix
- If given, prefix will be applied to the name of the output directories.
-
--time_interval
- Time interval to group images.
- Unit is seconds.
- Default value is
3600
(seconds.)
-
--time_start
- If given, the image will be grouped from given time by given
time_interval
. - Default value is set to the JD of the first image.
- If given, the image will be grouped from given time by given
- Simple preprocessor performs bias / dark / flat calibration.
- Full options are described here.
- Support GPU computing (based on Pytorch? or maybe just OpenCL?) for calibration, like GPUPhotometry.
- GPUPhotometry was also a simple preprocessing program utilizes GPU, but it does not support various options, and does not support Windows.
- Adding options for masterbias, masterdark, masterflat output.
- Using sum combiner.
- Even if exposure time of dark frames are different from each other, each frame cannot be weighted one by one, but just devided by exposure time of each dark frames, and summed.
- By this reason, it is strongly recommended to use multiple dark frames with same exposure time.
